Assuming the tests pass:
/lgtm

@lentzi90 or @EmilienM want to take a look? I prefer this to disabling the Flatcar tests.

I see one of 2 potential outcomes here:

• OpenStack decides not to support Flatcar's partition table, in which case we fix the Flatcar images
• OpenStack fixes the regression and we remove the workaround

Either way it's not directly relevant to CAPO and I'd prefer not to lose the Flatcar coverage in the meantime.

We are mixing things up I think. We do not see the issue with the flatcar image on main as far as I know. It only happens when we bump devstack to 2024.2. So this PR is not really testing that
