Subject: [PATCH] kdump.sh: send fence kdump message to other nodes in the
 cluster

In 2nd kernel, to prevent the crashed system from being fenced off,
fence kdump message must be send to other nodes in the cluster
periodically before dumping process.

We preserve every node's name in /etc/fence_kdump_nodes in the
initrd, so we parse this file and send notify them.
