   * Adds xdebug cookies, from request setup.

   * In order to debug web tests you need to either set a cookie, have the
   * Xdebug session in the URL or set an environment variable in case of CLI
   * requests. If the developer listens to connection on the parent site, by
   * default the cookie is not forwarded to the client side, so you cannot
   * debug the code running on the child site. In order to make debuggers work
   * this bit of information is forwarded. Make sure that the debugger listens
   * to at least three external connections.
   *
   * @param \Symfony\Component\HttpFoundation\Request $request
   *   The request.
   *
   * @return array
   *   The extracted cookies.
