Enable 'platform-integ-apps' application support

This commit enables a new application tarball by:
 - adding existence through the stevedore plugin framework
 - register it as a system app to that system overrides can be generated
 - provide initial overrides for the rbd-provisioner and
   ceph_pools_audit charts
 - updates the rbd-provisioner to support installation of multiple
   provisioners in the same cluster.
