Description: 

Entity type and field storage definition events are now dispatched when one of the create/update/delete operation occurs.

The event name constants are defined in the EventTypeEvents and FieldStorageDefinitionEvents classes. The dispatched events are EntityTypeEvent and FieldStorageDefinitionEvent respectively.

Two corresponding traits are available if the listeners need to implement the EntityTypeListenerInterface and FieldStorageDefinitionInterface: EntityTypeEventSubscriberTrait and FieldStorageDefinitionEventSubscriberTrait respectively.
