Set an affinity for ceph mgr and mons to be on my master nodes

[Devin Buhl]

This would be nice to know where they are scheduled in the future. It will require a cluster rebuild to make happen.

      placement:
        mgr:
          nodeAffinity: &nodeAffinity
            requiredDuringSchedulingIgnoredDuringExecution:
              nodeSelectorTerms:
                - matchExpressions:
                    - key: node-role.kubernetes.io/control-plane
                      operator: Exist
        mon:
          nodeAffinity: *nodeAffinity

Hi,
are you sure this affinity is right without a NoSchedule-toleration?

@acuntex works for me 🤷🏼 I do not taint my masters
