Description
Hi, DataX 团队：
我尝试用DataX连接阿里云上的sftp server，配置信息应该都是对的，用WinSCP是可以的，但是用DataX的时候，就会报这样的错误：
Unable to negotiate with 221.227.108.254 port 51852: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1
麻烦帮确认一下是不是DataX客户端用的key算法太旧了？

Research direction
Start at the ftpReader entry point and reproduce the SFTP connection using the reported server offer: diffie-hellman-group1-sha1, diffie-hellman-group14-sha1, and diffie-hellman-group-exchange-sha1. Compare the client's key-exchange configuration with the working WinSCP connection; done means the reported server can connect successfully without the negotiation error.
