> The ResourceOption to update NM's resource has two properties: Resource and 
> OvercommitTimeout. The later property is used to guarantee resource is 
> withdrawn after timeout is hit if resource is reduced to a value and current 
> resource consumption exceeds the new value. It currently use default value -1 
> which means no timeout, and we should make this property work when updating 
> NM resource.
