Return original error instead of negotiation one

**What this PR does / why we need it**:
When the requested type (eg. `text/html`) is not available and we're trying to hit an endpoint to which a user is for unauthorized we'll get 406, instead of 403. The reason for that is that, even if error happens we're trying to match the serializer, which fails and results in swallowing error, instead of returning raw json, for example. 

This fix returns raw json for such situations.

Fix AppArmor upgrade test

https://github.com/kubernetes/kubernetes/pull/52395 Introduced the `unconfined` AppArmor profile, but this feature should not be tested in the upgrade test since it doesn't exist prior to 1.9 (so the test always fails when checking it prior to the upgrade).

Reduce memory footprint of admission metrics

Fix #56061

Remove `SummaryVec` from all but the top level metric and reduce buckets for the histogram from 7 to 5.

For a small test cluster, the `Individual Memory Usage: kube-system kube-apiserver-kubernetes-master` grafana metric suggests showed the memory footprint of apiserver at 655MB before this change and 415MB after, suggesting this accounts for the vast majority of the ~200MB of memory increase found in #56061.

Increase log level of failed AWS public dns lookup

This constantly spams us because none of our nodes have a public IP. We
run kubelet at -v=2 as recommended.

The message is "Could not determine public DNS from AWS metadata." Debatable if this should even be logged at all, but I don't mind at a higher log level.
