Review comment:
I think the proper solution is to enforce this invariant in the
`InternalContainerResource` constructor (filtering out entries with a value of
`0` or to adapt the `equals` method to not check entries with a value of `0`).
Otherwise we might run into the situation that sometime in the future when the
user can specify the GPU constraints on an operator and he sets it to `0` that
the resources won't match.
