配置项参考手册 reportConsumerDefinition 默认值

https://github.com/apache/dubbo/blob/e915918e5c43319e1a7e2cab547685658d98b36a/dubbo-metadata/dubbo-metadata-report-nacos/src/main/java/org/apache/dubbo/metadata/store/nacos/NacosMetadataReport.java#L183

看着应该是`false`. 而且`MetadataReportConfig`里没这个字段，意思是放在`parameters`里？
但我在`shenyu`里没配置`dubbo.metadata-report`整个一项，又是会上报的。

Start with NacosMetadataReport.java at the linked line and compare it with MetadataReportConfig. Then inspect the Dubbo metadata-report configuration reference to determine how reportConsumerDefinition is represented and what behavior applies when dubbo.metadata-report is omitted. Done means the reference documents the default value and configuration location accurately.
