The EventDispatcherInterface is the central point of Symfony's event listener system.
Listeners are registered on the manager and events are dispatched through the manager.

Adds an event listener that listens on the specified events.
| \Symfony\Component\EventDispatcher\string | $eventName | |

| integer | $priority | The higher this value, the earlier an event listener will be triggered in the chain (defaults to 0) |

The subscriber is asked for all the events it is interested in and added as a listener for these events.
