Refactoring the DRA upgrade/downgrade testing such that it runs as Go test depended on supporting ktesting in the E2E framework. That change worked during presubmit testing, but broke some periodic jobs. Therefore the relevant commits from https://github.com/kubernetes/kubernetes/pull/135664/commits get reverted:c47ad64820DRA e2e+integration: test ResourceSlice controller047682908dktesting: replace Begin/End with TContext.Stepde47714879DRA upgrade/downgrade: rewrite as Go unit test7c7b1e1018DRA e2e: make driver deployment possible in Go unit tests65ef31973cDRA upgrade/downgrade: split out individual test steps47b613edede2e framework: support creating TContext The last one is what must have caused the problem, but the other commits depend on it.
