Refactor smoke tests

[jnummelin]

We need to refactor some/most of the smokes.

Duplication

There's lot of code duplication for some test lifecycle stuff like applying the CAPI yamls etc. We should really refactor all these out to common place.

Hard to debug on CI

Currently, when a smoke fails on CI, it's pretty impossible to say what went sideways. Yes, we do collect k0smotron controller logs but often times that does not really tell much. What we would need is also some state of thing, like a full dump of all the related objects. And possibly logs of other controllers. What I think in the end we'd need is basically a support dump like we do on k0s side for the smokes.

Move some of the standaloone k0smotron tests away from k0s bootloose suite

We don't really need that functionality, we should be able to run all the tests in similar way on top of kind.
