      Description

      SPARK-2099 added the ability to update helpful metrics like shuffle bytes read/written on the webui via a periodic heartbeat from executors. It omitted GC time metrics though.

      This ticket is for including GC times in the heartbeats.

      See the updateAggregateMetrics method here:
