snapshot problem

Hi,
I don't have a containerized deployment so I don't have anything to
compare, but my compute nodes have a ceph.conf and all required
keyrings in /etc/ceph/, maybe someone else can confirm that it's
missing and should be present in a kolla-ansible deployment. In the
meantime you could provide those files to the container and retry the
live snapshot.
