nacos 配置中心加载配置启动 dubbo 报 error

### 加载配置的代码
```
rootConfig := dubbo_config.NewRootConfigBuilder().
SetConfigCenter(dubbo_config.NewConfigCenterConfigBuilder().
SetProtocol("nacos").
SetAddress(ip). // 根据配置结构，设置配置中心
SetDataID(DataID). // 设置配置ID
SetGroup(Group).
Build()).
SetLogger(LoggerConfig).
Build()

if err := rootConfig.Init(); err != nil { // 框架启动
panic(err)
}
```
### 配置内容
```

**服务并不需要这两个配置，为什么要去加载它们？**

自查定位到这行：
https://github.com/apache/dubbo-go/blob/7bba076bc260950998dc0b320b20e48bcda2f296/registry/directory/directory.go#L485

https://github.com/apache/dubbo-go/blob/7bba076bc260950998dc0b320b20e48bcda2f296/registry/directory/directory.go#L509

https://github.com/apache/dubbo-go/blob/7bba076bc260950998dc0b320b20e48bcda2f296/registry/base_configuration_listener.go#L59

为什么这里设置监听用的 key 是 `url.EncodedServiceKey()+constant.ConfiguratorSuffix` ？不能在配置里设置吗？我没建立叫这个名的配置。
为什么 `listener.InitWith`里默认用`constant.Dubbo` ? 不能在配置里设置吗？ 我没这个group。
为什么这里一定要设置`listener`？我配置不会变动，不需要监听。

如果是我这样使用不对，请问建议的使用方式是怎样的？
