Allow binding full arguments map onto an object

[marceloverdijk]

Having a Query mapping like:

public Page<Season> seasons(@Argument Pageable pageable) {. .. }

and a corresponding class:

@Data
public class Pageable {

    private int first;
    private int offset
}

when querying:

query {
  seasons(first:5, offset:10) {
    ..
  }
}

the pageable object in the controller is null unfortunately.
I think the reason is that it will look for a pageable input variable and will not look for the individual first and offset fields.

Yes, @Argument looks for a name, either from the annotation or from the method parameter name. We need some way to express that not one but all arguments should be the source. Perhaps a separate annotation @Arguments.
