Add Support for jax-rs Response return type

[vegegoku]

This should allow us to define client interfaces in domino-rest like this

...
import jax.ws.rs.core.Response;
...
public interface FooResource {
    @POST
    @Path("foo/bar")
    Response create(Foo foo);
}

The problem with this is that the Response class does not implies any type information regarding the response body, so we need a way to describe the response body type for the annotation processor to generate proper deserializer.
