      Description

      For clusters with significant load on secondary nodes of replica set shards, the default secondary throttle mode (w:1) may not ensure that chunk migration doesn't interfere with all secondaries. Support other write concern "w" modes (1, 2, "majority") for this parameter to allow configurable throttling. Also the default is changed to { _secondaryThrottle: true } for chunk migration.
