golang升级etcd解决 grpc兼容性问题

golang升级etcd解决 grpc兼容性问题(最新方案，不依赖replace）

目前基于milvus-go-sdk开发项目， 其依赖grpc，最低版本要求 v1.27.0， 但框架中集成的etcd依赖的grpc版本是 v1.26.0

  1. 升级grpc到v1.27.0, 导致etcd不好用
  2. 维持grpc版本在v1.26.0, 导致milvus-go-sdk不好用。

遇到了各种报错

`golang` 调用 `etcdv3` 报错 `undefined: balancer.PickOptions`

go: github.com/coreos/[email protected]: parsing go.mod etcd 3.5

使用replace方法替换， 临时本地解决， 多项目依赖 replace，治标不治本！ 大部分解决方案都是基于此

一、 升级etcd到最新版本， 修改etcd调用方式

go get -u go.etcd.io/etcd/client/v3

二、 代码中修改etcd包引用方式

import "go.etcd.io/etcd/clientv3" 修改为  import "go.etcd.io/etcd/client/v3"
