python3 实现堡垒机功能（并发执行命令及上传下载文件）

转载请注明出处，欢迎提出宝贵意见，谢谢！

功能介绍：

1、主机分组
　　登录后显示分组主机及主机数量
　　选择主机组后显示该主机组下所有主机信息，主机名及IP
显示输入选择：
1、执行命令
利用线程并发组内所有主机同时执行命令，并将结果，返回
格式为：
----------------------host1------------------

----------------------host2------------------

----------------------host3------------------

----------------------host4------------------

2、传输文件
