Summary: Ref T2230. This is easily the worst thing I've had to write in a while. I'll leave some notes inline.
Test Plan: Ran `hg clone http://...` on a hosted repo. Ran `hg push` on the same. Changed sync'd both ways.

Summary: This is starting to get a bit sizable and it turns out Mercurial is sort of a beast, so split the VCS serve stuff into a separate controller.
Test Plan: Pushed and pulled an authenticated Git repository.
