    Description

      At the moment mongos sends a shardsvr request to each primary shard of each existing databse. To reduce the fan out degree of this command and increase efficiency mongos should send only one command to each primary shard that will in turn fetch the list of its databases from config server and check metadata consistency for each of them.
