[Beowulf] Bright Cluster Manager

I never used Bright.  Touched it and talked to a salesperson at a 
conference but I wasn't impressed.

Unpopular opinion: I don't see a point in using "cluster managers" 
unless you have a very tiny cluster and zero Linux experience.  These 
are just Linux boxes with a couple applications (e.g. Slurm) running on 
them.  Nothing special. xcat/Warewulf/Scyld/Rocks just get in the way 
more than they help IMO.  They are mostly crappy wrappers around free 
software (e.g. ISC's dhcpd) anyway.  When they aren't it's proprietary 

I install CentOS nodes and use 
Salt/Chef/Puppet/Ansible/WhoCares/Whatever to plop down my configs and 
software.  This also means I'm not suck with "node images" and can 
instead build everything as plain old text files (read: write SaltStack 
states), update them at will, and push changes any time.  My "base 
image" is CentOS and I need no "baby's first cluster" HPC software to 
install/PXEboot it.  YMMV
