Create ranks mapping file for slurm jobs

[amaslenn]

Summary

Always create ranks mapping file for slurm jobs by running extra srun command before actual test.

Test Plan

1. CI
2. Manual run with modified sbatch file where actual test is excluded (for the sake of speed).
   Single node, mapping-stdout.txt content (mapping-stderr.txt is empty).

Additional Notes

I was considering using pre-hook for this task, here is why I decided not to go with it:

1. Pre-hook is considered as verification, but here we need an action that is used for collecting extra info.
2. Pre-hook would require a status validation function.
3. With pre-hook + SlurmContainer job (or any other job) we won't be able to redirect output into file with "mapping" in the name, we can't control that.

I will approve again once unit tests are fixed
