Simplify HTTP client configuration properties by sharing common
settings for both blocking and reactive clients.
The `ClientHttpRequestFactorySettings` and `ClientHttpConnectorSettings`
have been merged to a single `HttpClientSettings` class. Properties
to configure common settings are available under:
`spring.http.clients`
Blocking and reactive settings have been moved to
`spring.http.clients.blocking` and `spring.http.clients.reactive`. With
currently only the factory/connector being configurable.
HTTP Service Client properties have also been rationalized under a
`spring.http.serviceclient.<group-name>`. Support for properties that
apply to all service clients and all Rest/Web Clients have been removed.
Support for `ApiVerionInserter` beans has also been removed in favor of
configuring the service group or builders directly.
Closes gh-47398
Create `spring-boot-resttestclient` and `spring-boot-webtestclient`
modules to hold test client auto-configuration and `TestRestTemplate`
code.
Previous these classes were contained in `spring-boot-resetclient-test`
and `spring-boot-webclient-test` which was incorrect since the `-test`
modules should hold code need to test the given modules, not supporting
test classes.
