title: How to control Doctrine Event subscriber priorities
body: <p>I have an entity which I have two separate event subscribers listen to postPersist and postUpdate events to trigger particular actions. In the EventDispatcher component in Symfony the listeners could have priority attached to them but I do not seem to find the priority option for Doctrine events. Is there a way to have the subscribers prioritized or Doctrine event dispatcher doesn't support it, I really can't seem to find the right option for that.</p>
