在grpc的包管理中碰到多个包的管理如何关联举个例子：
    项目名称crawler,自然文件夹的名称就是这个，这个是golang的定义

    D:\test2\crawler\proto\gen.bat

    1. protoc --go_out=plugins=grpc,import_path=./:../../ ./client/client.proto
    2. protoc --go_out=plugins=grpc,import_path=./:../../ ./global/entity.proto
    3. protoc --go_out=plugins=grpc,import_path=./:../../ ./server/server.proto

    例如上面：server.proto和client.proto都共同引用了entity.proto
    自己体会了
