Gateway timeout configuration

[chazex]

Describe the bug

1. GatewayConf.Timeout如果要设置超时，在yaml格式的配置文件中，该怎么写？ 我试了写8s, 8000都不可以。
2. GatewayConf.Timeout 和 GatewayConf.RestConf.Timeout 冲突了，因为RestConf是匿名的。这个无法通过配置文件配置了。只能在代码里面写。 2.1 GateConf.Timeout的生效位置是在使用grpcurl.InvokeRPC()的时候，使用这个参数构建了一个Timeout Context。 GatewayConf.RestConf.Timeout的生效位置有两个，一个是基于此参数配置了原生http.Server的ReadTimeout和WriteTimeout，另外一个是在http的Server端的http超时拦截器中。

我测试过，如果我们的业务逻辑处理时间超过GatewayConf.Timeout 或者 超过 GatewayConf.RestConf.Timeout，都会出现504的错误
