[torqueusers] Node Priority

If you use Maui, you have a lot of powerful tools to deal with that. 

The easiest way would be to specify MINRESOURCE node allocation, which 
puts the jobs on the nodes with the least resources that still meet 
the jobs constraints. That should automatically put all "normal" jobs 
on the small nodes.
Then you can add priorization with node features / classes / groups, etc. 
I'd also prioritize the jobs with requirements globally, and use the other
ones to backfill.
