Based on [1], this patch implements changes to the playbook which executes the cinder deployment in a play per host group, serialised to ensure that: 1. The services are changed in the right order. 2. The services remain available at all times during an upgrade. 3. Online data migrations are actioned once all versions of software are at the same levels. 4. If services are sharing a host/container then the role execution will not execute twice on the same host.
