… node is temoporarily unavailable (elastic#129391) During cluster upgrade, the anomaly detection jobs must be reassigned from one ML node to another. During this reassignment, the jobs transition through several states, including "opening" and "opened". If, during this transition, the master node becomes temporarily unavailable, e.g., due to reassignment, the new job state is not successfully committed to the cluster state. Therefore, once the new master became available, the cluster state was inconsistent: some anomaly detection jobs were opened, but their state got stuck as "opening". This PR introduces a retryable action for updating the job state to ensure that the job state is successfully updated and the cluster state remains consistent during the upgrade. Fixes elastic#126148
