docs: Redirect + Echo Server
  - Follows specified redirects -> /<redirects-count>
  - Redirects with specified response code -> /status/<response-code>
  - Echos final request URL, Method, Headers and Body
  
  @example
  var s = createRedirectServer();
  
  s.listen(3000, function() {
  console.log(s.port);
  s.close();
  });
