Remove docstring requirement that slurm job name is unique (#1813)
Remove docstring requirement that slurm job name is unique (#1813)

The slurm provider generates a unique slurm job name, based
on the job_name passed to submit() and a timestamp; the
job_name passed to submit() does not need to be unique, and
it looks like in fact the default "parsl.slurm" is used in
every use parsl makes of the slurm provider, which is
never unique in the multi-job case.
