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.
