 @param prefix [String] The require prefix. If the path is inside Faraday,
           then it will be prefixed with the root path of this loaded
           Faraday version.
 @param options [{ Symbol => String }] library names.

 @example

   Faraday.autoload_all 'faraday/foo',
     Bar: 'bar'

   # requires faraday/foo/bar to load Faraday::Bar.
   Faraday::Bar

 @return [void]
