- Kubeadm: instead of passing the etcd flag --experimental-initial-corrupt-check, set the InitialCorruptCheck=true etcd feature gate, and instead of passing the --experimental-watch-progress-notify-interval flag, pass its graduated variant --watch-progress-notify-interval.

- When using the conformance test image, a new environment variable `E2E_USE_GO_RUNNER` will cause the tests to be run with the new golang-based test runner rather than the current bash wrapper.
