> Auto scaling is triggered by marking pods as unschedulable. The core triggers
> the checks to mark pods unschedulable. The checks is based on the maximum
> resource quotas for the queues and the requested resources.
> The number of requests to mark outstanding can never exceed the resources
> amount available within the quota for the queues.
> If a request has unlimited resource types in a limited queue scale up will
> not be triggered due to failures in the headroom calculation. The headroom
> calculation for the resource type that is not limited will become negative.
> This then breaks the "fit in" check as the unlimited resource is now defined
> as a negative value.
