As QE have tried to test upstream CAPI pausing, we've hit a few issues with running the migration controller. & cluster capi operator on a real cluster vs envtest.

This card captures the work required to iron out these kinks, and get things running (i.e not crashing).

I also think we want an e2e or some sort of automated testing to ensure we don't break things again.

Goal: Stop the CAPI operator crashing on startup in a real cluster.

Non goals: get the entire conversion flow running from CAPI -> MAPI and MAPI -> CAPI. We still need significant feature work before we're here.
