Slurm version in compute node image is fixed to 20.02

[boegel]

After rebuilding a comptue node image, I noticed it has Slurm 20.02.5 installed, while the head node had Slurm 20.11.9 (latest from https://download.opensuse.org/repositories/home:/Milliams:/citc/EPEL_8_CentOS/x86_64/).

It seems like the Slurm version is being fixed to 20.02 in a couple of places:

• https://github.com/clusterinthecloud/ansible/blob/50051c846caa58bbeadca869c7edaaacc7969815/group_vars/all.yml#L8
• https://github.com/clusterinthecloud/ansible/blob/50051c846caa58bbeadca869c7edaaacc7969815/roles/slurm/molecule/compute/molecule.yml#L23
• https://github.com/clusterinthecloud/ansible/blob/50051c846caa58bbeadca869c7edaaacc7969815/roles/slurm/molecule/mgmt/molecule.yml#L24

I'm not sure they're all relevant/problematic, this is definitely something that should be sorted out.

I've worked around this by adding sudo dnf update -y slurm to /home/citc/compute_image_extra.sh and then rebuilding the compute node image.
