> Currently lazy preemption can't trigger an update on queue preemption metrics since the
update is only called in CapacityScheduler#completedContainerInternal which is not the only
way to be passed for all container completions. 
> This issue plans to move this update to LeafQueue#completedContainer to trigger an update
on queue preemption metrics for all container completions because of preemption.
