Dubbo Admin 标签路由功能未生效

[linkai0001]

• I have searched the issues of this repository and believe that this is not a duplicate.
• I have checked the REAMDE of this repository and believe that this is not a duplicate.

Environment

• Dubbo Admin version: 0.5.0
• Registry center detail (type and version): nacos1.2.1
• Operating System version: windows
• Java version: jdk1.8
• dubbbo version： dubbo3.1.4

Steps to reproduce this issue

1. 部署 dubbo admin ，调整 application.properties 配置， 支持 nacos 配置中心和注册中心

如下配置

server.port=18879
dubbo.protocol.port=18880
dubbo.application.qos-port=38880
admin.registry.address=nacos://10.32.52.57:8848?username=nacos&password=nacos
admin.config-center=nacos://10.32.52.57:8848?username=nacos&password=nacos
admin.metadata-report.address=nacos://10.32.52.57:8848?username=nacos&password=nacos
admin.registry.group=DEFAULT_GROUP
admin.config-center.group=DEFAULT_GROUP
admin.metadata-report.group=dubbo
admin.registry.namespace=public
admin.config-center.namespace=public
admin.metadata-report.namespace=public
admin.root.user.name=root
admin.root.user.password=root
admin.check.sessionTimeoutMilli=3600000

2. 通过配置提供者业务服务的“标签路由”，配置如下

enabled: true
force: true
runtime: false
tags:
  - name: gray
    addresses:
      - '10.32.52.57:28861'

3. 服务消费者设置RPC上下文
   RpcContext.getClientAttachment().setAttachment("dubbo.tag", "gray");

问题：
dubbo admin 的“服务查询”是存在相关业务服务的 rpc service . 看着整个 dubbo admin 的启动到配置都是正常且生效的。
但是标签路由未生效， 没有命中配置的节点，还是会进行节点的负载调用
