Celery integration

It would be cool to be able to request svcs for the lifetime of a Celery task. The idea of having this was actually what really drove the point home for me as to why svcs is an awesome idea; I have a Flask + Celery codebase and it would be amazing to be able to use utility functions that grab svcs in the correct way for themselves depending on which context they're called in.

Yes, providing a unified dependency abstraction is indeed the goal. The problem is, I know nothing about Celery. This is something a domain expert will have to at least design.
