    Description

      We added new accumulators like $topN, $bottomN, but because they are not in the category of the aggregation expressions or match expressions there's no tracking in the serverStatus() metrics for those.

      Add new section to serverStatus

      db.serverStatus().metrics.operatorCounters.accumulators

      Track all accumulator operators that are supported in $group and $setWindowFields
