There really needs to be a way to use env vars for setting params like SBATCH_xxx

[akesandgren]

Just like slurms src/sbatch/opt.c handles env vars before it is calling the API, there should be the same type of handling in pyslurm.
Either using the SBATCH_xxx env vars or pyslurm specific ones.

This is now supported via the new Job submission API (at the moment just for slurm 23.02, but it will be backported to a few earlier versions soon)

pyslurm however does not use the SBATCH_ prefix, but its own specific one, PYSLURM_JOBDESC_. Everything after the prefix must match an existing attribute in JobSubmitDescription. Loading the environment variables must be explicitly triggered, and is not done by default.

For an example, please check here
