VSCode 远程调试 Vitess

通过 Vitess 自带的 docker-compose 在本地拉起 Vitess 环境倒是很方便，但是调试起来很痛苦，本地编译的vtgate可以跑起来，连接到 compose 运行的 consul，但因为 vttablet 注册到counsul的地址是容器内的hostname，宿主机运行的vtgate会连接不上。同理，调试vttablet会更痛苦。于是尝试在服务器linux上local运行（参照这里，在 MacOS 上用vscode远程调试。

Linux 运行 Vitess

参考官方文档一步步执行，不过还是会踩到坑，和本地运行的kubernetes的etcd组件有端口冲突，尝试通过修改etcd启动端口绕过，修改了 env.sh和scripts/etcd-up.sh，这里是diff:
