defines the method to customize http server

[sniperwzq]

单体服务部署时需要支持热更新,一些开源方案如overseer等需要使用http Serve,gozero的internal.StartHttp是支持StartOption的,但是Server Start不支持设置,发起pr支持start时自定义StartOption

It doesn't work, because Start(...StartOption) doesn't meet the Service interface.

So the server cannot be added into a ServiceGroup.

I think you can use RunOption to achieve that.

不能用RunOption, server.Start时才创建了http.Server, rest.RunOption在MustNewServer的时候就调用了; 需求是让api的http server能接受另一个 net.Listener, 类似 svr.ListenAndServe要Serve一下

Would you please add unit tests?
