[I] druid-kubernetes-extensions unable to perform rolling update (druid)
jakubmatyszewski opened a new issue, #15233:
URL: https://github.com/apache/druid/issues/15233
### Affected Version
27.0.0
### Description
I've tried to update my existing druid instance to use `druid-kubernetes-extensions` ([extension](https://druid.apache.org/docs/latest/development/extensions-core/kubernetes/)), but I have realized that this doesn't allow rolling update. In fact it seems like it will be generating errors and restarting services as long as there is any pod still running without `druid.discovery.type=k8s` enabled.
I think the problem stems from [this lines of code](https://github.com/apache/druid/blob/b95035f183e193f24ceee57cc41d295918fe87ac/extensions-core/kubernetes-extensions/src/main/java/org/apache/druid/k8s/discovery/DefaultK8sApiClient.java#L83-L84) triggering exception when druid service pod is detected, but doesn't have labels required by this extension.
What I get in logs of services that I already updated is as follows:
```

```
I have tested this extension on test environment with exactly same configuration, but with all services started with `druid.discovery.type=k8s` and it runs smoothly, so it seems like the only difference that makes it fail is what I've described above.
