Feature Overview (aka. Goal Summary)  

The two-node SNO HA effort is basing its work around pacemaker & corosync. It would greatly facilitate their work if customers can easily add the required packages while.

Goals (aka. expected user outcomes)

Provide pacemaker, corosync, and deps to CoreOS Extensions

Documentation Considerations

This will need to be documented as part of the 2-node setup, but the documentation should indicate that these packages are ONLY supported for this deployment model. Not for general use.
