[Story] Scorecard test for built-in discovery

[ebaron]

We should revisit adding a Scorecard test similar to cryostat-recording that uses built-in Kubernetes discovery instead of a custom target. We encountered some strange networking failures on the Cryostat end when trying this previously: #698 (comment). Nevertheless, this is an important test to have so we should try to find some way to make it work, at least for 3.0+.

Depends on cryostatio/cryostat#238
