We changed sync to use multiprocessing for parallel work. This broke
the ssh proxy code as it's all based on threads. Rewrite the logic to
be multiprocessing safe.
Now instead of the module acting as a stateful object, callers have to
instantiate a new ProxyManager class that holds all the state, an pass
that down to any users.

We had ssh logic sprinkled between two git modules, and neither was
quite the right home for it. This largely moves the logic as-is to
its new home. We'll leave major refactoring to followup commits.
