pacemaker remote profile support
This support enables a base profile called pacemaker_remote which will allow the operator to automatically configure the pacemaker_remote service on such nodes. This manifest also automatically adds any pacemaker_remote nodes to the pacemaker cluster. Depends-On: I0c01ecb7df1a0f9856fdc866b9d06acf0283fa4f Depends-On: Ic0488f4fc63e35b9aede60fae1e2cab34b1fbdd5 Change-Id: I92953afcc7d536d387381f08164cae8b52f41605
