Support multi-process task scheduling

[roman-mazur]

Well, it was never told GoroService is supposed to work in a multi process environment...
Main Goro interfaces is goro.schedule(Callable). If we we introduce multiprocess features, this interface will have to be restricted to accept Parcelables only. This will cause usage issues.

But there is 2 different interfaces: Goro and BoundGoro.
Also, GoroService.taskIntent requires Parcelable task.
So, at the end, it is not really clear that:

GoroService is not supposed to work in a multi process environment...

I understand that having BoundGoro and GoroService.taskIntent simply implies that goro interacts with local service, but that makes a very little gain...
