New integration test runner

[nightkr]

There are a few things I'd like to see to help tighten the integration test loop:

• Live updates (tilt style)
• Templating (subsuming Beku)
• Snapshot/replay k8s apiserver interactions(?)

This is still quite exploratory for now, but I'm working on at least trying to define the theory a bit better...

( Might make sense to think in terms of multiarch for that ;) muscle memory activation )

Should we move this back to next or maybe even remove it from the board?

Feature request: Errors displayed at the bottom with the Pass/Fail summary (Kuttl is terrible for this, and I end up having to scroll far back through all the noise).
