Investigate changes in SERVER-41455: Support running $out or $merge from a secondary with writes to the primary

      Description

      Downstream Change Summary

      The downstream impact of this change was likely already considered as part of PM-1770, but I'm marking this as having downstream impact for completeness. Drivers need to do work to expose this feature to applications, but I believe that this work has been deferred until the 4.6 compatible driver releases. The feature should be documented, but I believe we are waiting to document it until driver support lands.

      Description of Linked Ticket

      It should be possible to perform reads from a secondary node and send the writes to the primary. If the read part of a pipeline is expensive but the write is not so expensive, this could help decrease load on the primary.
