title: Is there way to specify expiry when creating a celery task?
body: <p>Specifically I use <code>shared_task</code> decorator to create a celery task.
  I tried the obvious <code>@shared_task(expires=3)</code> but it doesn't seem to work.</p>
  
  <p>Is there a way to tell this task is supposed to expire ** seconds after it is received as you can do with <code>apply_async</code> in calling time?</p>
