Description

The design doc stated that the placeholder resources and the real resource ask should be the same. However we are not checking it, so it is possible to ask for more or less resources, what might cause some unexpected issues.

Also the resource cleanup is not working properly in this case.

For example if we have higher resources set for the placeholders than for the real pods, after the cleanup the resource difference still be there in the queue and node.
