Description

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 The later property is used to guarantee resource is withdrawn after timeout is hit if resource is reduced to a value and current resource consumption exceeds the new value.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.
