Changes:
1. Convert responseX to Request.responseX extension method.
2. TaskRequest now extends Callable<Response> instead of Callable<Unit>
3, AsyncTaskRequest wraps TaskRequest with support for callbacks. (What does it returns if it fails on async mode? I think it should return Response? instead. Currently it is TODO and returns Response()).
