Double counting when AWs dont have any pods running

[tardieu]

When AWs are running with no pods under it, there is a double counting of resources. As seen in the screenshot minikube resources are increased in MCAD accounting when AWs are dispatched and do not have any pods running. This will cause queued AWs to dispatch and will never run, the real resources are shown in the terminal section of the screenshot.

Derived from #415.
