The configureBackgroundTask command can be executed at either the shard level or the global level. To run it at a global scope, the user must connect to a MongoS process and issue the command against its admin database.

The goal of this ticket is to implement support for this command on MongoS. This includes adding the logic to broadcast the command to all current shards—i.e., to run configureBackgroundTask on the primary of each replica set.
