 Description   

"unsharded" collections should be a special case where a collection exists only on a single shard and is implicitly sharded by _id (or potentially a special empty-key value). This simplifies much of the sharding logic and eliminates much complexity handling changes between sharded and unsharded collection state.

calling this a dup of SERVER-939, since implementing this gets that.
