implicitlyCreateIndex defaults to true and when set to false, will not create new indexes while running the shardCollection command.

enforceUniquenessCheck defaults to true and when set to false, ignores uniqueness property when validating indexes for shardCollection.

Regardless of both settings, shardCollection should still return an error if there are no index that is compatible with the new shard key pattern.
