Make setup_gpfs.sh and mknsd.sh aware of NSD servers.
Both scripts now use nsd_server_common.bash to re-exec on the first
node defined in $NSD_SERVERS if that variable is set (to the list of
sofs_storage nodes by 50sofs.defconf). They also also include the NSD
servers in the file that is passed to mmcrnsd and mmcrfs.
setup_gpfs.sh includes any NSD servers in the list of nodes for the
GPFS cluster, using them as the primary and secondary GPFS servers.
setup_gpfs.sh just sources mknsd.sh to avoid duplication of logic.
