> Job may be stuck for reasons such as:
> - hitting queue capacity
> - hitting user-limit,
> - hitting AM-resource-percentage
> The first queueCapacity is already shown on the UI.
> We may surface things like:
> - what is user's current usage and user-limit;
> - what is the AM resource usage and limit;
> - what is the application's current HeadRoom;
