 * invalidation to implementing state handlers that do not write to the cluster state, e.g. role mappings.
 * These additional transformation steps are implemented as separate async operation after the validation of
 * the cluster state update steps (trial run in {@link org.elasticsearch.reservedstate.service.ReservedClusterStateService}).
