If we’re given no resources, dump all of Chef’s built ins otherwise, if we have a path then extract all the resources from the cookbook or else do a list of built in resources
@param arguments [Array, String] One of more paths to a cookbook or a resource file to inspect @param complete [TrueClass, FalseClass] Whether to show properties defined in the base Resource
class @return [String] JSON formatting of all resources
