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 reduces the size of the test/e2e/framework itself. Because it does not
dump anything anymore by default, E2E test suites must set their own dump
function or set the original one by importing
"k8s.io/kubernetes/test/e2e/framework/debug/init".
