All code must use the context from Ginkgo when doing API calls or polling for a
change, otherwise the code would not return immediately when the test gets
aborted.
This addresses a problem caused by
https://github.com/kubernetes/kubernetes/pull/112043: because the AfterEach
which invokes AllNodesReady always runs, including tests that skipped early,
those tests ran into a nil pointer access. This increased the size of log
files. The tests still worked.
The "todo" packages were necessary while moving code around to avoid hitting
cyclic dependencies. Now that any sub package can depend on the framework, they
are no longer needed and the code can be moved into the normal sub packages.
