Subject: 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.
