module-setup.sh: setup fence kdump environment

This patch is used to setup fence kdump environment when building kdump
initrd:
1. Check if it's cluster and fence_kdump is configured.
2. Get all the nodes in the cluster and pass them to 2nd kernel via
   /etc/fence_kdump_nodes
3. Setup network interface which will be used by fence kdump notifier in
   2nd kernel.
4. Install fence kdump notifier (/usr/libexec/fence_kdump_send) to
   initrd.
