[GitHub] [dubbo] beimx opened issue #5742: Dubbo2.7.5 使用Zookeeper元数据中心，元数据未上报
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
- [ ] I have checked the [FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate.
### Environment
* Dubbo version: 2.7.5
* Zookeeper version: 3.4.14
* Operating System version: macos
* Java version: 1.8
### Steps to reproduce this issue
1. 按官方文档搭建provider，两种方式：annotation/xml
2. 分别配置
```xml
<dubbo:metadata-report address="zookeeper://127.0.0.1:2181"/>
```
```java
@Bean
public MetadataReportConfig metadataReportConfig() {
MetadataReportConfig metadataReportConfig = new MetadataReportConfig();
metadataReportConfig.setAddress("zookeeper://127.0.0.1:2181");
return metadataReportConfig;
}
```
3. 应用正常启动
4. Consumer端正常调用
4. 观察Zookeeper节点数据，元数据节点/dubbo/metadata 未创建
### Expected Result
元数据正常上报
### Actual Result
元数据节点在Zookeeper上未创建，元数据未上报
> 将dubbo版本号更改为2.7.4.1、2.7.3，代码或配置未改动，元数据正常上报

@chickenlj @mercyblitz 应该是 metadata-type 这个属性默认是local导致的这个问题，是不是可以在配置了dubbo:metadata-report address，metadata-type没有配置的情况下，将metadata-type属性默认设置为remote？这样能解决兼容问题，低版本的项目升级到2.7.5都需要增加metadata-type为remote的配置才能解决兼容性问题，容易出错
