No, it doesn't matter for this test but I see how this could be confusing. Done.

Test is now redundant. I'll change limit ranges to have both min and max.

I was thinking how pod limit and container limit will work together. Currently, if we trim due to podLimit, we give each of the containers limits proportionally to the current recommended resources, right? But then it might turn out that we have to trim to the containerLimit anyway and we end up with some unused podLimit and another container will have unnecessarily trimmed resources. But I guess it is sort of an edgecase anyway.

As decided offline we're going to do the simple thing for now and try to do something smarter if we see need to.
