> 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.
