python使用paramiko模块实现ssh远程登陆上传文件并执行

程序执行时需要读取两个文件command.txt和ipandpass.txt。格式如下：

command.txt:
threadnum:1
port:22
local_dir:hello_mkdir
remote_dir:hello_mkdir
alter_auth:chmod 755 hello_mkdir
exec_program:./hello_mkdir

ipandpass.txt:
ip username password

程序中的队列操作是修改的别的程序，写的确实不错。
该程序亦正亦邪，如果拿去做坏事，我先声明与我无关，我只是分享我的代码罢了。
希望有兴趣的同志们来讨论技术应用。
这其中用到了paramiko，队列，多线程，后续也会写一些这三个方面的东西。欢迎批评指正。
其实这个程序有些地方还有待优化。
