Okay, you are right. I misspoke related to metrics - they will come from the
NMs -> TimelineAggregator.
But the life-cycle events of container should definitely originate at the RM;
NMs don't even know many of them. And given it is just the life-cycle events
for containers, I think we are good w.r.t scalability. More like 5K writes per
second, let's include them here.
