Update provision_slurm.py.j2 to fix logic in mk_slurmuser_batch. This previously did not add any users if one user in the list was a member of 'default'

allow provision_slurm to take a path to the lockfile so its on a directory shared between managment nodes

speed up the default slurm provisioing by running groups of users rather than adding each user individually
