      Description

      Now that all chunk operations run in specialized config server commands, those commands can just do their multi-doc transaction writes directly in a single WUOW, there's no need to rely on applyOps/doTxn machinery. Doing this for 4.0 would allow us to remove support for atomic applyOps in 4.0, which is something the repl team is quite interested in.
