      Description

      Downstream Change Summary

      We added a new accumulator operator called $accumulator. This allows user-defined functions (Javascript) to run in a $group, $bucket, or $bucketAuto stage.

      Description of Linked Ticket

      Implement the $accumulator operator, which will let users create their own accumulators in $group.

      Restrict this new operator to FCV 4.4.
