Creates a DiscoveryClientRouteLocator that loads route definitions from a DiscoveryClient (like Eureka), as well as from properties. A route is created for each serviceId from the DiscoveryClient. As new services are added, the routes will be refreshed.

The above filter translates Servlet request information into OkHttp3 request information, executes an http request, then translates OkHttp3 reponse information to the Servlet response. WARNING: this filter might have bugs and not function correctly.

Post filters typically manipulate the response. In the filter below, we add a random UUID as the X-Foo header. Other manipulations, such as transforming the response body are much more complex and compute intensive.
