Kubernetes releases are now generating provenance attestation files describing the staging and release phases of the release process and artifacts are verified as they are handed over from one phase to the next.
This final piece completes the work needed to comply with Level 1 of the [SLSA security framework](https://slsa.dev/) (Supply-chain Levels for Software Artifacts).

- `/test/e2e/framework`: Adds a flag `non-blocking-taints` which allows tests to run in environments with tainted nodes. String value should be a comma-separated list. ([#81043](https://github.com/kubernetes/kubernetes/pull/81043), [@johnSchnake](https://github.com/johnSchnake))
