      Downstream Change Summary

      Added two server status metrics on mongoD:
      cursor.totalOpened - the total number of cursors that have been opened so far. Differs from cursor.open.total in that cursor.open.total is the total number of currently opened cursors, whereas this new metric is the number of cursors that have been opened until this point.

      cursor.moreThanOneBatch - the number of cursors that have returned more than one batch (i.e. have called getMore)

      Description of Linked Ticket

      This could help us understand how often resumable queries would be useful.
