[slurm-users] Keep CPU Jobs Off GPU Nodes

[Frank Pari]

Well, I wanted to avoid using lua.  But, it looks like that's going to be
the easiest way to do this without having to create a separate partition
for the GPUs.  Basically, check for at least one gpu in the job submission
and if none exclude all GPU nodes for the job.

Now I'm wondering how to auto-gen the list of nodes with GPUs, so I don't
have to remember to update job_submit.lua everytime we get new GPU nodes.
