    rgmanager/lvm.sh:  Fix bug bz242798
    
    Allow a machine to fence itself in the event that it
    cannot deactivate logical volumes.  (The user must
    explicitly enable this option.)  This is useful in cases
    where one machine in the cluster looses connectivity to
    its resources, but the others don't.  The machine fences
    itself and the service moves to another machine.
