Remove non-containerized pacemaker resources on upgrade

Adds upgrade_tasks to remove the pacemaker resources using the
ansible-pacemaker module.

Resources are disabled and removed in step2 (called only on
bootstrap node) and then the cluster stop is moved to step3

The existing systemd/service call is kept but only to disable
services after they are disabled/deleted from the cluster.
