Allow nodes to appear in more than one group/partition

[jovial]

Prior to this change slurmctld would fail to start if adding nodes to multiple partitions e.g:

openhpc_slurm_partitions:
    - name: allnodes
      groups:
        - name: alfa
        - name: beta
      partition_params:
        Priority: 50
      default: YES
    - name: alfa
      partition_params:
        Priority: 100
    - name: bravo
      partition_params:
        Priority: 100

This change tracks all nodes that already have a NodeName entry and will not add again.

Can the main README.md be modified please to remove the entry:

• Nodes may not appear in more than one group.

Happy to merge then, CI passed on rerunning one failed task.

Thank you this is very useful!
