    Adds pacemaker update_tasks for Pike minor update workflow

    Adds update_tasks for the minor update workflow. These will be
    collected into playbooks during an initial 'update init' heat
    stack update and then invoked later by the operator as ansible
    playbooks.

    Current understanding/workflow:
     Step=1: stop the cluster on the updated node
     Step=2: Pull the latest image and retag the it pcmklatest
     Step=3: yum upgrade happens on the host
     Step=4: Restart the cluster on the node
     Step=5: Verification: test pacemaker services are running.
