RollbackHook defines the "rollback middleware". A function that gets a Rollbacker and returns a Rollbacker. For example: 

hook := func(next ent.Rollbacker) ent.Rollbacker {
	return ent.RollbackFunc(func(ctx context.Context, tx *ent.Tx) error {
		// Do some stuff before.
		if err := next.Rollback(ctx, tx); err != nil {
			return err
		}
		// Do some stuff after.
		return nil
	})
}
