Add resources for major upgrade in Pacemaker scenario

Add Heat software deployments to be used to upgrade major versions of
OpenStack on the controller nodes. All controller services are taken
down while the upgrade is in progress.

The new updated yum repositories should be configured by another process
e.g. the deployment artifacts transfer via Swift.
