[FEATURE] Allow port forwarding in ssh tunnel without double-ssh

[cwill747]

Title

Add ability to forward a port from an ssh session without sshing into the secondary device

Platform

N/A

Is it related to an issue?

I think this is probably related to #866 but I couldn't grok what that person was specifically asking for. I'd like the ability to just expose a port of a remote machine (RDP, in my case) through an ssh tunnel - but I don't want the tunnel to try to ssh into that secondary Windows device (there's no ssh there) - I just need to use the top-level tunnel as a bastion

This is essentially replicating
ProxyCommand ssh -L 8000:%h:3389 foo@bar.com in an ssh config

The Solution

I imagine that I could either create a Tunnel in the SSH section of a jumpbox that didn't try to ssh into the remote device.
