ceph based cinder storage backends

OpenStack Ocata changes the behaviour of cephx key management for ceph based
cinder storage backends; as a result, nova-compute units must now have copies
of the key used by the cinder backend for managing ceph storage. To support
sharing of these keys, users must add a relation between the cinder-ceph and
nova-compute charms:

.. code:: bash

juju add-relation nova-compute cinder-ceph
