Set ceph key when using manila ceph backend

Manila ceph driver reads ceph's client configuration
(keyring is the most important) from ceph.conf file
(or any other file set by cephfs_conf_path). ceph.conf
should be updated with keyring location.

If ceph is deployed by tripleo then also manila ceph key
is added into ceph and ceph filesystem is created.
