Add proxy/redirect option #18

Add a way to pass a list of servers that have to be visited prior to the final server. Eg. in the destination parameter add a field "proxy" that contains a list of intermediate steps that need to be visited before accessing the final server. This is useful in the context of VPN networks where you need to access a VPN entry server from which you can access the actual server.

Kind of like:

ssh -N -L 11111:finalhost:22 user@middlehost

and

ssh -p 11111 user@localhost

Implementing the tunneling in Python with paramiko would add quite a bit of code 😭 And people usually establish the tunnel or VPN once, outside of the each tool they use.

So this is possible but I don't want to 😳
