Git integration for Grouper configs

Just some ideas I had while working with a customer. When provisioners, gsh templates, or other configs are managed in the UI, the history is stored in the UI. But if you want these exported on a regular basis to version control, it's a manual process.

(1) A script, maybe an external gsh batch script, to export configs into local files which are under version control
(2) Optionally add Git as an external system; maybe needs an api key

Maybe just item #1 is good enough for user needs?
