python脚本实现jenkins批量构建多分支job发布

随着微服务项目越来越多，每一次上线发布很多个构建job要手动构建很费时费力，所以能自动咱就不手动。

脚本环境基于python3，需要安装的模块是python-jenkins这个api库来说实现！关于api库使用请参考官方文档：API reference — Python Jenkins 1.1.1.dev1 documentation

脚本是通过遍历文本里的构建job名称和构建参数来实现批量构建，把构建完成的信息结果是保存输出到output.log文件里。

如果是多分支流水线job，job_name改为: "name/branch".例如：job为：test，分支为：dev，job_name="test/dev"
