 Description   

Due to some current limitations of the transaction machinery, SERVER-81937 is going to introduce a very complex flow with additional hops between router and shards to support the atomic creation of a collection entry on local+sharding catalog.

Purpose of this ticket is to simplify such flow and get rid of additional hops once the transaction machinery will support adding participants from a shard and writing directly shard-to-shard without having to pass by the router.
