Port to Drupal 8

In progress repo https://github.com/msankhala/redirect_after_logout

I have worked on it.

Following tasks are done :

1. Created settings/configuration form
2. Changed code in .module file
3. Created permissions file
4. Created links file
5. Created services file for event subscriber

Following are the remaining tasks, it would be very helpful if someone can review the tasks done by me and could take remaining tasks as well

1. Created event subscriber

In Drupal 7 version hook_drupal_goto_alter was used, in Drupal 8 we will have to use event subscriber for the same.

I have written the subscriber but the code doen not see to be proper

public function checkRedirection(FilterResponseEvent $event) {
    $response = $event->getResponse();
    if ($response instanceOf RedirectResponse) {
      $destination = &drupal_static('redirect_after_logout_user_logout');
      if ($destination) {
        $config = \Drupal::config('redirect_after_logout.settings');
        $logout_message = $config->get('redirect_after_logout_message', '');
        if (!empty($logout_message)) {
          $destination = $destination . '?logout-message=1';
        }
        $response->setTargetUrl($destination);
      }
    }
  }

This function needs to be reviewed.

2. Created schema and install files

PFA the patch file.
