      If a ShardingDDLCoordinator throws an exception during its construction phase, before to actually persist its state document on disk, it will reach the onCompletion task and will try to delete its state document, since this document doesn't exists the PrimaryOnlyServiceOpObserver::onDelete() won't be triggered and the instance won't be released from the POS.
