    Fix migration across apps when using VMs created from image

    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',
    allowing all nova-compute apps to use the same ceph auth.

    This patch also includes the charmhelpers sync
    from PR: #840
