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

Hi [~sjlee0]
Similar to the current plan for RM, planning to have a separate TimelineAggregator for NM
and placing it in NM context or in some new class like NMMetricsPublisher.
and on different container life cycle events publish ATS entities/events using it. Based on
current approach all the app aggregators are in auxillary service and auxillary service cannot
capture all life cycle events & metrics, hence i presume we should have per NM TimelineAggregator
too.
Is there any other approach planned as this is not captured in any jira's or in the doc.
