Support audit diff for error requests #79
Description
Description
We can try to infer the diff (although not exact) by reading the RequestObject field and comparing it against the original object state. However this requires caching each resourceVersion of an object in the database.
User story
An admission webhook gets a lot of requests, most of which failed. As the admission webhook owner does not know the component that created these requests, audit diff would help them diagnose why the admission webhook rejects them.
