Currently the behaviour of changing the source config option on the ceph*
charms is not equivalent to changing the openstack-origin option on the
OpenStack charms.

I've commented on Darryl's bug report with a proposed solution of using a
upgrade action to allow an upgrade to be rolled across units within a
cluster, rather than changing the config causing an upgrade on all units in
parallel, allowing for an upgrade without and outage in the cluster.
