Does it make sense to support a way to wire up HTTP interface clients with @RestClientTest? Example:

@HttpServiceClient("hello")
public interface HelloClient {

    @GetExchange(value = "/hello", version = "2")
    String hello();
}
@RestClientTest(HelloClientTest.class)
class HelloClientTest {

    @Autowired
    private HelloClient helloClient;

    @Autowired
    MockRestServiceServer mockRestServiceServer;

    @Test
    void hello() {
        mockRestServiceServer.expect(requestToUriTemplate("http://localhost:8080/hello?version={version}", 2))
                .andRespond(withSuccess("Hello There!", MediaType.TEXT_PLAIN));
        assertThat(helloClient.hello()).isEqualTo("Hello There!");
    }
}

I was able to get this to work in this Sample Repository by adding HttpServiceClientAutoConfiguration to AutoConfigureWebClient. This doesn't work when you define more than one HTTP client interfaces. Maybe it could use the components defined on the annotation to pick which client to wire up? Or maybe a new @HttpServiceClientTest?
