Deprecate plan runner fixture and all its variants

Migrate remaining modules to the new testing framework

Deprecating the old runners is great, I'm just not sure we want to add inventory for everything: whenever the resource changes they break, and often you end up needing to remove stuff fromt he inventory, or figure out why some attribute changed. Happened twice to me lately and I lost a lot of time over something that was WAI.

Agreed. Most of the new inventories reflect what we were already testing using python assertions. I did add a few here and there but I tried to keep them simple and asserting only the critical bits.

We should definitely fix/remove/improve those cases where you find things WAI that are causing false positives.
