[BUG] [Slurm role] munge key

[remyd1]

Hi,

The slurm role needs to be launched twice to:

1. Ansible role: install the munge package,
2. Generate the key manually,
3. Ansible role: configure slurm.

It would be more helpful if the ansible role generates the key itself through the command or shell module, allowing to launch the Slurm role only once.

Best regards

EDIT: to avoid an idempotent break on the controller, when should be used to check if the munge key already exists or not.

Dear @remyd1

Yes, you are right about this issue. Natively, munge keys were generated with a dd command, and so didn't need the munge package. I will investigate this, best solution would be to have munge key inside inventory.
