Trying to implement an AsyncResponseTransformer

@aesteve I think I found a little bug, which appears when using the transformer without invoking setResponseHandler

@Override
public void onResponse(ResponseT response) {
    // this.responseHandler == null if setResponseHandler is not invoked
    this.responseHandler.ifPresent(handler -> handler.handle(response));
}

Thanks for your reports, I've merged it.
