small swift HA fix, rysnc over swift_internal_vip

whichever node owns the swift_internal_vip should be considered the
"primary" swift node.
fencing ipmilan and dependency fixes

Use local modified version of quickstack::pacemaker::stonith::ipmilan
until upstream pacemaker::stonith::ipmilan is updated.  This version
determines the node to use on the fly for the parameter
pcmk_host_list.  Support for the lanplus parameter is also added.

Make sure fencing is configured (for fencing_type of fence_xvm or
fence_ipmilan) before trying to add cluster resources.
