      Add change stream specific throughput metrics on mongoS (see project design document section "Decision: Process-Level Change Stream Cursor Metrics / Throughput"):

      • metrics.changeStreams.cursor.docsReturned(already exists for query stats)
      • metrics.changeStreams.cursor.bytesReturned
      • metrics.changeStreams.cursor.batchesReturned(already exists for query stats)

      Design notes:

      • The docsReturned, bytesReturned, and batchesReturned should come from mongoS (router) pipeline creating the batches.
