Our CI machines happen to have 1 fully allocatable CPU for test workloads. This is really, really the minimal amount. But still should be sufficient for the tests to run the tests; the CFS quota pod, however, does create a series of pods (at time of writing, 6) and does the cleanup only at the very end the end. This means pods requiring resources accumulate on the CI machine node. The fix implemented here is to just clean up after each subcase. Doing so the cpu test footprint is equal to the higher requirement (say, 1000 millicores) vs the sum of all the subcases requirements. Doing like this doesn't change the test behavior, and make it possible to run it on very barebones machines.
