[slurm-users] Create users

[Douglas Jacobsen]

At one point in time we would also use the job_submit.lua to add users,
however, I cannot recommend it in general since job_submit runs while locks
are held within slurmcltd, which could have dramatic performance or even
functionality impacts if there are delays in adding the user.
