Have GitFS auto discover new envs for pillar_roots

[kenatbasis]

Just like how file_roots and gitfs work, I'd like to be able to point pillar_roots at a git repo, and have envs automatically created from new branches.

This is in the context of having many throwaway envs: gitfs + file_roots lets me create envs simply by branching, but I still have to manually modify the master config and restart it to add a pillar_roots env, which is problem with multiple dev teams.

Yes, this would be a cool feature to add, though we should probably hide it behind a config option to retain backwards compatibility. Pillar can have sensitive data so having a more well-defined set of environments to be made available is a useful feature that we want to retain.

Implementing this now.

Essentially, abstracting fileserver away from just doing states, subclassing it for StatesFileserver and PillarFileserver, and abstracting each of the file server backends to not be state-specific.

It'll be mostly backwards compatible; I'll leave out the part of having old config variables map to the new ones.
