> During downscaling there are two kinds of POD requests which can lead to POD
> deletion as it is identified as excess requests by the dynamic allocation:
> * timed out newly created POD requests (which even haven't reached the Pod
> Pending state, yet)
> * timed out pending pod requests
> The current implementation fails to delete a timed out pending pod requests
> when there are not enough timed out newly created POD requests to delete but
> there are some non-timed out ones.
