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.
