> When the applicationMaster wants to change(increase/decrease) resources of an allocated container, resource utilization is an important reference indicator for decision making. So, when AM call NMClient.getContainerStatus, resource utilization needs to be returned.
> Also container resource utilization need to report to RM to make better scheduling.
> So put resource utilization in ContainerStatus.
