Update SNAPSHOT to Edgware.SR5

Example uses the same value of eureka.client.serviceUrl.defaultZone for all peers. The eureka server knows who it is and doesn't attempt to replicate to itself [1], so this simplification will work.

+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

-NOTE: You may need to increase the amount of memory available to Maven by setting
-a `MAVEN_OPTS` environment variable with the value `-Xmx512m -XX:MaxPermSize=128m`
+NOTE: You can also install Maven (>=3.3.3) yourself and run the `mvn` command
+in place of `./mvnw` in the examples below. If you do that you also
+might need to add `-P spring` if your local Maven settings do not
+contain repository declarations for spring pre-release artifacts.
 
-The `.settings.xml` is only required the first time (or after updates
-to dependencies). It is there to provide repository declarations so
-that those do not need to be hard coded in the project poms.
+NOTE: Be aware that you might need to increase the amount of memory

+build succeed, please raise a ticket to get the settings added to
+source control.
 
 For hints on how to build the project look in `.travis.yml` if there
 is one. There should be a "script" and maybe "install" command. Also
 look at the "services" section to see if any services need to be

-=== Pull Requests
-
-Spring Cloud is released under the non-restrictive Apache 2.0 license,
-and follows a very standard Github development process, using Github
-tracker for issues and merging pull requests into master. If you want
-to contribute even something trivial please do not hesitate, but
-follow the guidelines below.
-
-==== Sign the Contributor License Agreement
-Before we accept a non-trivial patch or pull request we will need you
-to sign the
-https://support.springsource.com/spring_committer_signup[contributor's
-agreement].  Signing the contributor's agreement does not grant anyone
-commit rights to the main repository, but it does mean that we can
-accept your contributions, and you will get an author credit if we do.
-Active contributors might be asked to join the core team, and given
-the ability to merge pull requests.
-
-==== Code Conventions and Housekeeping
-None of these is essential for a pull request, but they will all help.  They can also be
-added after the original pull request but before a merge.
-
-* Use the Spring Framework code format conventions. If you use Eclipse and you follow
-  the ``Importing into eclipse'' instructions below you should get project specific
-  formatting automatically. You can also import formatter settings using the
-  `eclipse-code-formatter.xml` file from the `eclipse` folder. If using IntelliJ, you can
-  use the https://plugins.jetbrains.com/plugin/6546[Eclipse Code Formatter Plugin]
-  to import the same file.
-* Make sure all new `.java` files to have a simple Javadoc class comment with at least an
-  `@author` tag identifying you, and preferably at least a paragraph on what the class is
-  for.
-* Add the ASF license header comment to all new `.java` files (copy from existing files
-  in the project)
-* Add yourself as an `@author` to the .java files that you modify substantially (more
-  than cosmetic changes).
-* Add some Javadocs and, if you change the namespace, some XSD doc elements.
-* A few unit tests would help a lot as well -- someone has to do it.
-* If no-one else is using your branch, please rebase it against the current master (or
-  other target branch in the main project).
-
 === Working with the code
 If you don't have an IDE preference we would recommend that you use
-https://www.springsource.com/developer/sts[Spring Tools Suite] or
-https://eclipse.org[Eclipse] when working with the code. We use the
-https://eclipse.org/m2e/[m2eclipe] eclipse plugin for maven support. Other IDEs and tools
-should also work without issue.

+We recommend the http://eclipse.org/m2e/[m2eclipse] eclipse plugin when working with
 eclipse. If you don't already have m2eclipse installed it is available from the "eclipse
 marketplace".
 
+NOTE: Older versions of m2e do not support Maven 3.3, so once the
+projects are imported into Eclipse you will also need to tell
+m2eclipse to use the right profile for the projects.  If you
+see many different errors related to the POMs in the projects, check
+that you have an up to date installation.  If you can't upgrade m2e,
+add the "spring" profile to your `settings.xml`. Alternatively you can
+copy the repository settings from the "spring" profile of the parent
+pom into your `settings.xml`.
+
 ==== Importing into eclipse without m2eclipse
 If you prefer not to use m2eclipse you can generate eclipse project metadata using the
 following command:
 
 [indent=0]
 ----
-	$ mvn eclipse:eclipse
+	$ ./mvnw eclipse:eclipse
 ----
 
 The generated eclipse projects can be imported by selecting `import existing projects`
 from the `file` menu.
 
-==== Adding Project Lombok Agent
-
-Spring Cloud uses [Project
-Lombok](https://projectlombok.org/features/index.html) to generate
-getters and setters etc. Compiling from the command line this
-shouldn't cause any problems, but in an IDE you need to add an agent
-to the JVM. Full instructions can be found in the Lombok website. The
-sign that you need to do this is a lot of compiler errors to do with
-missing methods and fields, e.g.

-
-This project provides Netflix OSS integrations for Spring Boot apps through autoconfiguration
-and binding to the Spring Environment and other Spring programming model idioms. With a few
-simple annotations you can quickly enable and configure the common patterns inside your
-application and build large distributed systems with battle-tested Netflix components. The 
-patterns provided include Service Discovery (Eureka), Circuit Breaker (Hystrix), 
-Intelligent Routing (Zuul) and Client Side Load Balancing (Ribbon).
-
-
-== Features
-
-* Service Discovery: Eureka instances can be registered and clients can discover the instances using Spring-managed beans
-* Service Discovery: an embedded Eureka server can be created with declarative Java configuration
-* Circuit Breaker: Hystrix clients can be built with a simple annotation-driven method decorator
-* Circuit Breaker: embedded Hystrix dashboard with declarative Java configuration
-* Declarative REST Client: Feign creates a dynamic implementation of an interface decorated with JAX-RS or Spring MVC annotations
-* Client Side Load Balancer: Ribbon
-* External Configuration: a bridge from the Spring Environment to Archaius (enables native configuration of Netflix components using Spring Boot conventions )
-* Router and Filter: automatic registration of Zuul filters, and a simple convention over configuration approach to reverse proxy creation
