> used.
> - Check if labels can be accessed by the queue when submit an app with
> labels-expression to queue or update ResourceRequest with label-expression
> - Check labels on NM when trying to allocate ResourceRequest on the NM with
> label-expression
> - Respect labels when calculate headroom/user-limit
