   * Redirects the user to a URL after a form has been processed.
   *
   * After a form is submitted and processed, normally the user should be
   * redirected to a new destination page. This function figures out what that
   * destination should be, based on the $form_state and the 'destination'
   * query string in the request URL, and redirects the user there.
   *
   * The result of \Drupal\Core\Form|FormStateInterface::getRedirect()
   * determines where to redirect the user. See the possible return values
   * listed there. If the result is FALSE, then the user will not be redirected.
   *
   * Here is an example of how to set up a form to redirect to the path 'user':
   * @code
   * $form_state->setRedirect('user.page');
   * @endcode
   * And here is an example of how to redirect to 'node/123?foo=bar#baz':
   * @code
   * $form_state->setRedirect('entity.node.canonical',
   *   array('node' => 123),
   *   array(
   *     'query' => array(
   *       'foo' => 'bar',
   *     ),
   *     'fragment' => 'baz',
   *   ),
   * ));
   * @endcode
   *
   * @param \Drupal\Core\Form\FormStateInterface $form_state
   *   The current state of the form.
   *
   * @return \Symfony\Component\HttpFoundation\RedirectResponse|null
   *
   * @see \Drupal\Core\Form\FormBuilderInterface::processForm()
   * @see \Drupal\Core\Form\FormBuilderInterface::buildForm()
