---------------------------------------------------------------

What if the cluster provider doesn't want to use the existing {{AppLogAggregator}} at all, then they need to ask all their user to set the customized aggregator in {{LogAggregationContext}} for all jobs. Why don't we make the default/fallback implementation also configurable?
