Only allow anonymous auth for configured endpoints.

Hello @vinayakankugoyal 👋, Enhancements team here.

Just checking in as we approach enhancements freeze on 02:00 UTC Friday 14th June 2024 / 19:00 PDT Thursday 13th June 2024.

This enhancement is targeting stage alpha for v1.31 (correct me, if otherwise)

Here's where this enhancement currently stands:

• KEP readme using the latest template has been merged into the k/enhancements repo.
• KEP status is marked as implementable for latest-milestone: v1.31. KEPs targeting stable will need to be marked as implemented after code PRs are merged and the feature gates are removed.
• KEP readme has up-to-date graduation criteria
• KEP has a production readiness review that has been completed and merged into k/enhancements. (For more information on the PRR process, check here). If your production readiness review is not completed yet, please make sure to fill the production readiness questionnaire in your KEP by the PRR Freeze deadline of Thursday 6th June 2024 so that the PRR team has enough time to review your KEP.

For this KEP, it looks like we still need to do the following:

• Merge KEP-4633: Only allow anonymous auth for configured endpoints #4634 before the enhancement freeze date and update KEP status to implementable, looks like we need review from one more approver.

The status of this enhancement is marked as at risk for enhancement freeze. Please keep the issue description up-to-date with appropriate stages as well.

If you anticipate missing enhancements freeze, you can file an exception request in advance. Thank you!

[vinayakankugoyal]

Hi @prianna - thanks a lot for the heads up. We were granted the PRR approval #4634 (comment) and the reviewers have agreed that we can set the status to implementable. I am expecting this to be merged this week.

[vinayakankugoyal]

@prianna - The KEP was merged as implementable in milestone 1.31 with a PRR approval. Are we all good on the KEP freeze front?
