Add visibility for "Audit" type verdicts

User Story

As a visitor of the hubble-ui, I expect to see verdicts of the type "Audit" when running Cilium in Audit Mode, so I can validate my policies.

Background

When I first experimented with Cilium, I didn't want to harm any traffic/usability and enjoyed using hubble-ui to get a sense of how traffic flows. However, once I established rules, I couldn't see the difference when adding Policies although visible within the hubble-cli (hubble observe --verdict AUDIT -f).

This would be very useful, to the point where I'd say it may block some users from adopting cilium.
