/kind bug

What steps did you take and what happened:
I pivoted an openstack cluster from a management cluster to another. Due to the nature of this process, the parent CAPI cluster initializes paused, all children get moved and then the cluster gets resumed.

When an OpenstackServer is linked to a paused CAPI cluster, reconciliation ends without requeue. As there are not watchers for the parent cluster in OpenstackServer reconciler, the resource will not be reconciled anymore (unless restarting CAPO or modifying the object).

What did you expect to happen:
CAPO would either detect the parent cluster of an openstack server changed (thus reconciling it again) or it would retry with Requeue in

Anything else you would like to add:
