Get MockRestServiceServer by ImportHttpServices group in tests

[ilia1243]

@ImportHttpServices internally configures and creates a RestClient, and corresponding RestClient.Builder is seemingly not exposed anywhere. This makes it difficult to distinguish builders in MockServerRestClientCustomizer to access the necessary MockRestServiceServer.

Could you consider adding a new RestClientHttpServiceGroupConfigurer with the similar functionality as in MockServerRestClientCustomizer that will provide a MockRestServiceServer for each HttpServiceGroup?

This is very similar to, or perhaps a duplicate of, #49746.

They are both related to http services and their testing using MockRestServiceServer.

The issue 49746 is about how to properly configure @RestClientTest to access at least one MockRestServiceServer.

This issue is about easier access to different MockRestServiceServer for each http service group, no matter whether @RestClientTest or @AutoConfigureMockRestServiceServer are used.
