Igor Motov f985638bba Add a generic way of checking version before serializing custom cluster object
In #22313 we added a check that prevents the SnapshotDeletionsInProgress custom cluster state objects from being sent to older elasticsearch nodes. This commits make this check generic and available to other cluster state custom objects if needed.
