Operator helm chart is not idempotent - certificates are renewed on each "helm upgrade"?

Dear maintainers,

I have been playing with CockroachDB and the helm charts. It looks like the operator chart creates new TLS certificates each time the user runs a `helm install` or `helm upgrade`.

This might make it harder in GitOps enviroments, where the chart would be shown as "out of sync" or "syncing" on every sync (i.e. every couple of minutes).

I found no way to disable this recreation or to have the operator chart use existing user-provided charts.

Kind Regards,
Johannes
