[slurm-users] Create users

Until now I had thought that the most elegant way of setting up Slurm
users would be via a PAM module analogous to pam_mkhomedir, the simplest
option being to use pam_script.

When in Denmark this year (hello Ole!) I looked at pam_mkhomedir quite closely.
The object was to automatically create home directories, not for Slurm
users. What I found was that pam_mkhomedir uses a precompiled
executable, rather than triggering a script which you would expect. So
it is difficult to customise.
there is an Oddjob based version   https://access.redhat.com/discussions/903523
However in the past I have found the Oddjob version unreliable on an
HPC cluster, so used the standard pam_mkhomedir

pam_script does look to be the answer here. And I do admit to not
having heard of it.
