Stale key detection to avoid a false preexisting split brain condition

(Linux only)

It may happen that while the cluster nodes go offline, the network connectivity between the nodes and the coordination points is lost. If such an event occurs with a server-based fencing configuration, some stale keys may be left on one or more coordination point servers (CP servers). The presence of a stale key might create a preexisting split brain condition, after which manual intervention is required to bring the cluster online. The CP server functionality is enhanced to identify the false preexisting split brain condition that occurs due to the presence of such stale keys. The CP server informs the vxfen module about the stale keys, and the module performs its arbitration to continue the smooth operation of the cluster.
