No cleanup mechanism for GIT_PILLAR

[stratusjerry]

Description of Issue

There is no automated or manual cleanup mechanism for cached GIT_PILLAR.

Setup

Create a git pillar repo using the syntax

ext_pillar:
- git:

Restart the master and run salt-run git_pillar.update
Delete the existing git pillar repo config and create a new git pillar.
Restart the master and run salt-run git_pillar.update
You will see directories for both in /var/cache/salt/master/git_pillar/ but there is no way via salt-run, or ext_pillar config to cleanup old cached git pillars.
