With a global parameter of type json e.g. dns with value {"servers":["1.1.1.1"]}, it should not be possible to override the property with a raw string value e.g. "9.9.9.9" because it may break policy generation.

• enforce that a overriding property be of the same type as the overridden
• warn about any existing inconsistencies within a node or group that overrides a property
• warn heavily when changing the type of a property which already has overrides, knowing the hierarchy global parameter > group > node for properties inheritance. The user should have a list of affected groups or nodes when making such change
