Job priority via the 'nice' job parameter

[TorecLuik]

Nice - Users can adjust the priority of their own jobs by setting the nice value on their jobs

If we add this optional parameter to run_workflow, we add a possibility for (future) BIOMERO scripts to limit / raise job priority based on the user or group that starts the BIOMERO script.

This is a cheap alternative to allowing per-user SSH keys (with possibly different roles/priorities/powers inside Slurm).

[TorecLuik]

Like the system nice, positive values negatively impact a job's
priority and positive values increase a job's priority
● Only privileged users can specify a negative value
● The adjustment range is +/-2147483645.

We can already add it in general via the config similar to cellpose_job_gres=gpu:1g.10gb:1; cellpose_job_nice=48939834`
