> Currently the interval with which NM publishes container CPU and memory metrics is tied
to {{yarn.nodemanager.resource-monitor.interval-ms}} whose default is 3 seconds. This is too
aggressive.
> There should be a separate configuration that controls how often {{NMTimelinePublisher}}
publishes container metrics.
