This will allow us to install the slurm deb packages from https://github.com/IKIM-Essen/EMCP-slurm/releases/tag/21.08.5-2ubuntu1 when we're ready to upgrade.

I've added a couple of things which should make deploying and upgrading easier:

The slurm deployment is now in its own playbook.
The slurm installation role now includes a slurm_upgrade variable which, when enabled, stops all daemons before proceeding with the deployment. This should reduce the risk of leaving the cluster in an inconsistent state if something goes wrong during the deployment.

Tested upgrading from v19 to v21. The playbook works, but the new slurmctld doesn't support the old state files.
