Update of Pod labels fails when going from 1.22.4 to 1.23.0

[burmanm]

What happened?

When updating a cluster with datacenterNameOverride in use, the v1.23.0 does not see all the pods it should update to the latest labels and instead causes the StatefulSet to go out of sync (and operator not seeing which pods it should start).

As a workaround, one can modify the pod labels to match the updated StatefulSet definition (namely, the cassandra.datastax.com/datacenter).

What did you expect to happen?

No response

How can we reproduce it (as minimally and precisely as possible)?

Make cluster with v1.22.4 using datacenterName (which is different from dc.Meta.Name) and then update that to v1.23.0

cass-operator version

1.23

Kubernetes version
