> ContainerAllocationExpirer sets the expiration interval to be RMConfig.CONTAINER_LIVELINESS_MONITORING_INTERVAL
but uses AMLIVELINESS_MONITORING_INTERVAL as the interval.  This is very different from what
AMLivelinessMonitor does.
> There should be two configs RMConfig.CONTAINER_LIVELINESS_MONITORING_INTERVAL for the
monitoring interval and RMConfig.CONTAINER_EXPIRY_INTERVAL for the expiry.
