[discuss] fail annotation parsing fast and report errors as events

[jrudolph]

To address problems like #5282 it would be good if processing errors that prevent an ingress from progressing to be logged as a proper events.

The difficulty here is how to deal with annotation-related errors. Right now many of those are logged and ignored but might lead to downstream problems.

For this POC, the annotation processing is failed early as soon as a broken annotation is found and the error will be reported as an event.

I cannot foresee the full consequences of an approach like this. How could it be improved?

Update: I simplified the suggestion by creating an event whenever the annotations report an error in the "Denied" field. So, the actual behavior is not changed only the reporting.

Hi @jrudolph. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
