tests: group and parametrize tests

Instead of creating a dedicated test and using the same testinfra
module we can group them into a single test to avoid multiple ansible
connections and testinfra module execution.
This patch also adds parametrize pytest decorator when possible.
Finally fixing some flake minor issue.
