接手了一个SpringCloud项目，默认已经集成了Sentinel，但是后来发现网站访问量很小，而且服务器资源也不够用了，需要禁用Sentinel来释放内存资源。

理论上觉得应该在哪里有个开关，但是找了一小时才找到官方文档（算是文档吧）：

https://github.com/alibaba/spring-cloud-alibaba/blob/2.2.x/spring-cloud-alibaba-starters/spring-cloud-starter-alibaba-sentinel/src/main/resources/META-INF/additional-spring-configuration-metadata.json

第一个配置就是了：

  "properties": [

      "type": "java.lang.Boolean",
      "defaultValue": true,

    },
