Currently, the CollectionShardingState is kept on a map, which tracks the set of {{Collection}}s on the server. We should instead make it a decoration on the Collection in order to avoid the separate map lookup and mutex.
This also better ties the lifetime of a collection with that of its sharding state and allows us to potentially prevent direct drop of sharded collections.
