Create a Shard
Shards can only created with this API for collections that use the 'implicit' router. Use SPLITSHARD for
collections using the 'compositeId' router. A new shard with a name can be created for an existing 'implicit'
collection.

Delete a Shard
Deleting a shard will unload all replicas of the shard, remove them from clusterstate.json, and (by default)
delete the instanceDir and dataDir for each replica. It will only remove shards that are inactive, or which have no
range given for custom sharding.
