Subject: Add support for Ceph as a Cinder and Nova backend

This commit aims to add support for Ceph as a cinder and a nova backend.

  * Allows creation of Ceph pools from heat (Default: volumes, vms)
  * Creates the proper ceph user and inject the keys
  * Applies the proper configuration in cinder.conf and nova.conf
  * Enable the backend out of the box
