[slurm-users] introduce short delay starting multiple parallel jobs with srun

[Yakupov, Renat /DZNE]

Hi Gennaro,

they are all tasks within the same job... If I start multiple jobs, I can just use --begin.
I think I found a solution using shell PID $$, which is unique for each task. 

Best,
Renat.

according to the NEWS file, native jobarray support was introduced in
version 2.6.0pre1 ... bad luck.

You can still save the first SLURM_JOB_ID somehow and make the
following jobs compute their sleep time using:

$((SLURM_JOB_ID - FIRST_SLURM_JOB_ID))
