interceptor bindings on RestClient interfaces don't work with RestClient Reactive

[Ladicek]

Describe the bug

If I have a RestClient interface like this:

@RegisterRestClient(baseUri = "http://localhost:8080")
@CircuitBreaker(requestVolumeThreshold = 4)
public interface HelloClient {
    @GET
    @Path("/ft-hello")
    String hello();
}

and use RestClient Reactive together with Fault Tolearnce, the circuit breaker doesn't work. If I put the @CircuitBreaker annotation on the hello method, the circuit breaker works just fine.

This is caused by RestClient Reactive not copying annotations from the interface itself to the generated class (though annotations from RestClient methods are copied to the generated methods).

Expected behavior

Interceptor bindings declared on the RestClient interface itself work with RestClient Reactive.

Actual behavior

Interceptor bindings declared on the RestClient interface itself don't work with RestClient Reactive.

Interesting twist: the generated class extends RestClientReactiveCDIWrapperBase, which defines a few methods. In a naive implementation, these methods would get intercepted as well, and that should not happen.

#22774 will help with that problem. I have a fix ready, but it needs to wait for that PR.
