      getDestinedRecipient() is called by OpObserverImpl for all write operations and returns boost::none when there isn't an ongoing resharding operation. Calling CollectionShardingState::get() and CollectionShardingState::getCollectionDescription() even when sharding isn't enabled adds overhead. ShardingState::enabled() can be used to detect whether the server was started with --shardsvr to avoid the performance regression for stand-alone mongods and replica sets.
