Expected Behavior

pipeline deployment deletion should kick off reconcile func, so that the pipeline deployment can be recreated.

Actual Behavior

no recreation of deployment, though deployment is registered:

	err = c.Watch(
		&source.Kind{Type: &appsv1.Deployment{}},
		&handler.EnqueueRequestForOwner{
			IsController: true,
			OwnerType:    &op.Config{},
		})
	if err != nil {
		return err
	}

Steps to Reproduce the Problem

1. install the operator, remove the either deployment of the pipeline
2. pipeline deployment can not be revived.
3. reconcile func is not called.
