      Description

      Group coordinator does not reset heartbeat timer when commit request is received.
      This may lead to unnecessary session timeouts when a consumer sends
      sync commit requests so frequently that causes heartbeat requests to be
      delayed.

      Presumably (as I do not know Kafka code well):
      Commit requests (v1 and v2) have all data fields for a heartbeat request,
      If they are taken as effective as heartbeat requests, we should have
      better group stability.

      [For reference]
      previous discussions in: users@kafka.apache.org
      mail title: consumer group, why commit requests are not considered as effective heartbeats?
