To Reproduce Steps to reproduce the behavior:

1. Provision a NodeSet and a compute node.
2. Scale in the NodeSet as described in the official docs: https://docs.redhat.com/en/documentation/red_hat_openstack_services_on_openshift/18.0/html/maintaining_the_red_hat_openstack_services_on_openshift_deployment/assembly_scaling-data-plane-nodes#proc_removing-a-Compute-node-from-the-data-plane_scaling
3. (optionally) Remove the BMH and associated secrets
4. Create a new NodeSet
5. Try to add the compute node to the new NodeSet (keeping the hostname)
6. Run a OpenStackNodeSetDeployment
7. The deployment of the node is stuck with the message{{ 'TLSInput error occured in TLS sources Object openstack/ovn-default-compute2 is already owned by another Ope nStackDataPlaneNodeSet controller openstack-data-plane'}}

Expected behavior

• The compute node is added to the new NodeSet and the deployment finishes successfully.

Device Info (please complete the following information):

• Tested on RHOSO 18.0.15

Bug impact

• Unable to "reprovision" nodes by migrating to different NodeSets in order to manage their configuration independently.

Known workaround

• Remove the CertificateRequests, Certificates and Secrets associated to the node after removing it from the original NodeSet.
