 Description   

Sharded aggregations currently have different code paths for unsharded collections passthrough and pipelines which only target a single shard. Conceptually we shouldn't need to distinguish between the two cases to prepare for a world where unsharded collections are tracked in the config server.

charlie.swanson I've left this in needs scheduling but wouldn't be opposed to including as part of the MR epic, as follow-up work for SERVER-42942.
