This patch is adding a feature for an option to copy different
ceph configuration files and corresponding keyrings for cinder,
glance, manila, gnocchi and nova services.
This is especially useful when the deployment uses availability
zones as below example.
- Individual compute can read/write to individual ceph
cluster in same AZ.
- Cinder can write to several ceph clusters in several AZs.
- Glance can use multistore and upload images to
several ceph clusters in several AZs at once.
