Can't run 2 jobs at the same time with pdwfs-slurm

[JCapul]

Describe the bug

Running a second job with pdwfs-slurm when one has been launched on the same machine (for instance same login node) and is still running results in an errors in both jobs.

To Reproduce

Run twice the same job on the same machine (e.g. the example provided: ior_slrum).
Both jobs show some errors upon finalization related to a connection to Redis:34000 and the pdwfs.session file.

Expected behavior

No error should occur and both jobs should complete gracefully.
