[slurm-users] upgrading slurm to 20.11

[Brian Andrus]

You need to step upgrade through major versions (not minor).

So 19.05=>20.x

I would highly recommend going to 21.08 while you are at it.
I just did the same migration (although they started at 18.x) with no 
issues. Running jobs were not impacted and users didn't even notice.
