Description

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.
