rolling_update: Remove ceph aliases

ceph aliases have been introduced in stable-3.2 during the ceph
deployment. On master this has been removed but we don't handle
this removal in the upgrade from stable-3.2 to master via the
rolling_update playbook.
Also remove the task from purge-docker-cluster missing from
d9e7835
