      When talking to an older server that doesn't support write commands, mongos needs to convert writes into GLEs. The controls that were hooked to old write commands should migrate to the new write commands.

      + triggering splits
      + logic for switching batches into writes + gle's
      + logic for detecting when to use the item above
      + Draining the writeback listener
      + isMaster.maxWireVersion and initShardVersion
