This is part of the transition to using framework/log instead
of the Logf inside the framework package. This will help with
import size/cycles when importing the framework or subpackages.
Some commands used in tests are Linux specific and do not exist
or do not behave the same on Windows nodes. This can cause those
tests to fail on Windows nodes.
Replaces the mentioned commands with ones that behave the same on
both Linux and Windows.
Use the same pattern everywhere in the e2e test
harness, use busybox (from dockerhub) instead
of using the one from k8s.gcr.io registry.
