add keepalive to ssh connection

[sander76]

Thanks for this great library!

One thing I am experiencing though is my ssh connection dropping. Is it possible to add something like a keepAlive functionality like this ?:

I myself am no go developer, so I am not sure what to do.

Sander.

Inspiration or usage of https://github.com/davrodpin/mole as the underlying ssh is possible as it supports keep-alive and retrying a dropped connection.
