Rodrigo Barbieri 8c3549d828 [v2] Fix migration across nova-compute apps using ceph 
This change reworks previous changes [1] and [2] that had
been respectively reverted and abandoned.

When using the config libvirt-image-backend=rbd, VMs
created from image have their disk data stored in ceph
instead of the compute node itself.

When performing live-migrations, both nodes need to
access the same ceph credentials to access the VM's
disk in ceph, but this is currently not possible
if the nodes involved pertain to different
nova-compute charm apps.

This patch changes app name sent to ceph to
'nova-compute-ceph-auth-c91ce26f', a unique name common to
all nova-compute apps, allowing all nova-compute apps to
use the same ceph auth.

This change also ensures newly deployed nodes install
the old credentials first on ceph-joined hook,
and then supercedes it with the new credentials
on ceph-changed hook, therefore also retaining
the old credentials.
