URL: https://github.com/apache/dubbo-go-pixiu/issues/891
在 v1.1.0 版本的 gateway 和 pixiu proxy 可以从 hello world 示例里面创建 http 服务，从而访问到正常数据。

在 v1.2.0 版本对 gateway 进行优化改进，对 pixiu pod 进行支持内置热加载方式去完成，不再重启。

进入 pixiu-gateway 的日志里面去查看热加载相关的
新的服务的创建（http.yaml）会被 pixiu-gateway 生成新的 configmap，主要需要更新
routes、clusters、endpoints 然后触发热加载 POST http://podip:18380/-/reload
热加载处理先更新触发日志更新，然后是 RouteReloader 路由配置，最后是 ClusterReloader 去更新 ClusterManager
完成添加或更新 cluster
和更新 endpoints；所以请求到达需要满足：1. 路由匹配；2. clustermanager 找到 cluster；3. 找到 endpoint
即可返回 200
