Fix Cleanups for keystone/placement/nova

* Check KEYSTONE_DEPLOY flag and cleanup appropriately
* When we stop process, we should not wipe uwsgi config we should
  remove files only on cleanup
* We should not call cleanup *BEFORE* configure, we are just wiping
  out the uwsgi ini files
* cleanup_placement should be called from clean.sh
