Adds post_upgrade_tasks for any service post-upgrade ansible tasks

This adds a new config/deployment per role that will come after any
post deploy steps. It drives the same ansible config as the
upgrade_tasks but instead collects the post_upgrade_tasks for any
service in the given role.

The workflow is upgrade_tasks, then post deploy steps (either
puppet/ or docker/ depending on the env) and then the
post_upgrade_tasks added here.

This is added to the pacemaker/cinder-volume.yaml service for now
see the bug below for more info
