      Description

      Mongos isn't guaranteed to forward txnNumbers received from clients for commands that aren't supported in multi statement transactions, so it can't rely on shards to reject them. Instead mongos should check itself that received commands with txnNumbers are allowed in a transaction, ideally using the same validation code as mongod.
