Microprofile rest client - Can't inject config/beans to providers

[snowdrop-bot]

Describe the bug
Any provider added to rest client via @Provider annotation is unable to inject config bean or any other application scoped bean.

@RegisterRestClient
@RegisterProvider(RequestFilter.class)
public interface EchoService {....}

And example the provider impl:

public class RequestFilter implements ClientRequestFilter {
  @Inject
  AppConfig config;  //is always null

  @Inject
  SomeBean bean; //is always null

  @Override
  public void filter(ClientRequestContext requestContext) throws IOException {...}

Expected behavior
Config or application scope bean injected and not null

Actual behavior
Any bean injected via @Inject is alway null (no errors in logs during argumentation nor during runtime.

To Reproduce
Steps to reproduce the behavior:

1. Use reproducer: https://github.com/marcinczeczko/quarkus-rest-providers-reproducer
2. mvn compile quarkus:dev
3. curl http://localhost:8080/echo
4. Check the logs - the injected config & app bean shows null reference

Configuration

• See reproducer
