  Use Kuddle as a config provider for a single file, if you want to load a directory see
  Kuddle.Config.Distillery.DirectoryProvider instead.

  This is a variant of the Config.Provider specifically used for Distillery

  ## Example

      release :default do
        set config_providers: [
          {Kuddle.Config.Provider, [
            path: {:system, "PATH_TO_CONFIG", "/default/path/to/kdl/config"}
