      Description

      We should account for the degree of parallelism that the query runs with on a backend to avoid overadmitting too many parallel queries.

      We could probably simply count the effective degree of parallelism (max # instances of a fragment on that backend) toward the number of slots in admission control (although slots are not enabled for the default group yet - see IMPALA-8757).
