Copy slurm config from CoD into slurm-factory

Refer to https://gitlab.rc.uab.edu/rc/rc-slurm

We want to keep the latest copy for quick access because the slurm.conf is templated from the ansible role in cod_slurm in CRI_XCBC project. We can't use the ansible template if we need a slurm config to quickly experiment with slurm features.
