Add hosting, serving, and push policy options to repository edit

Summary:
Basically straight from D7391. The differences are basically:

  - Policy stuff is all application-scope instead of global-scope.
  - Made a few strings a little nicer.
  - Deleted a bit of dead code.
  - Added a big "THIS DOESN'T WORK YET" warning.

Test Plan: See screenshots.
