Clarify if MBR/MBW should see annotations from interfaces and concrete classes

Given

```
public interface RootInterface {
@GET
@Produces
String get();
}

public class RootImpl implements RootInterface {
@A
String get();
}
```

should MBR and MBW see @GET + @Produces only or @GET + @Produces + @A where @A is a custom non-JAX-RS annotation ?

Proposal: update the Annotation Inheritance spec text accordingly, probably makes sense to avoid merging but I'm not sure

Thanks
