Timed wait for futures

Summary:
It might be useful to be able to wait for some time (but not forever) on a
future, so this is a shot at doing that. It's a very heavyweight implementation, however.

Since the current interface for waitWithSemaphore doesn't really make sense if
the timeout fires, change it to return a Future<T>.

Test Plan: unit tests
