Rocks: Add Torque 5.x Roll

Torque 5.x Roll

• Source: ftp://ftp.uit.no/pub/linux/rocks/torque-roll/5.4.0

The Rocks way of installing the roll is as usual to reinstall your frontend
and compute nodes, but you can also use the chain of commands to install a 
new roll on an existing frontend (with or without a previous version of the roll):

# rocks add roll torque-5.4.0-1.x86_64.disk1.iso
# rocks enable roll torque
# rocks create distro
# rocks run roll torque | sh
# reboot

After the the frontend comes back up you should do the following to populate the node list:

# rocks sync config

then kickstart all your nodes

# rocks run host /boot/kickstart/cluster-kickstart

After the nodes are reinstalled they should automatically pop up in the queueing system.
