homogenize class parameters names and descriptions for each resource
States should share the same class_parameter name for a given resource.
A resource always has a named parameter (or two). But its related states often use a different name for their class_parameter.
file state absent(target) -> file state absent(path)
file state from_template(destination) -> file state from_template(path)
This homogenization makes GM clearer and easier to deal with when it comes to rudderlang conversions (into/from JSON notably)
