在services中修改annotations：kt-virtual-environment/rule: 后不会更新vs，需要重新删除svc重新创建。

在services中修改annotations：kt-virtual-environment/rule: 后不会更新vs，需要重新删除svc重新创建。

测试过修改svc中Prefix字段或allowOrigin字段

```
kt-virtual-environment/rule: '{"Match":[{"Uri":{"Prefix":"/"}}],"corsPolicy":{"allowOrigin":["*"],"allowCredentials":true,"allowHeaders":["app-key","xxx"],"allowMethods":["GET","POST","PUT","DELETE","PATCH","OPTIONS"]}}'
```

之后 virtual-env-operator 多出如下日志

```
[Info] 2022-02-18 11:04:27 Adding Service gateway
[Info] 2022-02-18 11:04:27 Trigger reconcile VirtualEnvironment
[Info] 2022-02-18 11:04:32 Send reconcile signal
[Info] 2022-02-18 11:04:32 Receive reconcile request with name: virtualenv
[Info] 2022-02-18 11:04:32 Unmarshal route rule successful
```

但vs中配置并未更新

删除svc重建后vs更新，virtual-env-operator 日志如下

```

Start by reproducing an annotation update on a Service, changing the Prefix or CORS fields in kt-virtual-environment/rule, and inspect the virtual-env-operator reconcile logs. The issue is done when the corresponding VirtualService configuration reflects the changed rule without deleting and recreating the Service.
