Don't restart Pods on changes to static users Secret

[sbernauer]

In #833 we will enable restart-controller for all Trino Pods.
However, this will mean that the hot-reloading of the static users secret will stop working, as the Pod will be restarted on every Secret change.

One possible solution is to add a label/annotation to the Pod to instruct restart-controller to ignore changes to a given Secret (this needs to be implemented in commons-operator first)
