To support the Manila/CephFS scenario with a TripleO managed Ceph deployment we need to add a CephMDS role in TripleO.
The changes submitted for this use bug/1644784 topic branch https://review.openstack.org/#/q/status:open+topic:bug/1644784
We should have now a new CephMDS service optionally deployed in the overcloud; we can move forward patching the configuration of Manila to use it.
Verified.
