不知道如何正确使用 watch.Interface，参考k8s源码: 

https://github.com/kubernetes/kubernetes/blob/release-1.20/pkg/volume/csi/csi_attacher.go#L444-L487

或者： 

watcher, err := cli.Watch(ctx, objctList)
if err != nil {
	return fmt.Errorf("watch error:%v", err)
}
defer watcher.Stop()

for {
	select {
	case event, ok := <-watcher.ResultChan():
		if !ok {
			log.Warningf("watch channel had been closed")
			break
		}

		switch event.Type {
		case watch.Added, watch.Modified:
			...
		case watch.Deleted:
			...
