 Description   

In Atlas, sharded cluster expose a several mongoses and the drivers implement their own logic to decide which mongos to forward the request to.

Unfortunately, our tests do not mimic this, instead they almost always execute all the commands through the same mongos.

This big lack of coverage didn't allow us to spot bugs like SERVER-76489.
