[slurm-users] Drain a single user's jobs

Hi Mark,

I *think* you might need to update the user account to have access to that
QoS (as part of their association). Using sacctmgr modify user <foo> + some
additional args (they escape me at the moment).

Also, you *might* have been able to set the MaxSubmitJobs at their account
level to 0 and have them run without having to do the QoS approach - but
that's just a guess on my end based on how we've done some things here. We
had a "free period" for our clusters and once it was over we set the
GrpSubmit jobs on an account to 0 which allowed in-flight jobs to continue
but no new work to be submitted.
