SLURM Priority Adjustment

Since priorities were not working for those users who use Memex less frequently and in smaller batches of submitted jobs, these parameters were adjusted:

PriorityWeightFairShare=20000
PriorityWeightTRES=CPU=1000,Mem=2000,GRES/gpu=3000

As a result gres/gpu was added to:

AccountingStorageTRES=cpu,mem,energy,node,billing,fs/disk,vmem,pages,gres/gpu

This functionality changes in SLURM 19+, but our current version is 18.08 which is the latest version packaged with OpenHPC 1.3.

Update: AcctGatherFilesystemType was also enabled for lustre.
