Enhance KubePodNotReadyControlPlane alert definition (gardener#8361)

* Enhance KubePodNotReadyControlPlane alert definition Prior to this change, this alert could fire when an etcd compaction job was started, because its status could be e.g. `Completed`, rather than Ready. Co-authored-by: Istvan Zoltan Ballok <istvan.zoltan.ballok@sap.com> Co-authored-by: Jeremy Rickards <jeremy.rickards@sap.com> * Remove curator filter for KubePodNotReadyControlPlane alert This was apparently a leftover from a CronJob that's no longer in use. --------- Co-authored-by: Istvan Zoltan Ballok <istvan.zoltan.ballok@sap.com>
