Add support for ssh agent forwarding

[SidShetye]

Tried out webSSH on my iPhone and liked it enough to purchase it. Thanks for making a quality app.

I do have a request - please support SSH agent forwarding (explained). I use it to run sudo on target machines without re-typing complex passwords all the time. There is a server side configuration is explained here (SSH Agent for sudo). but it does require the client (webssh) to support ssh agent forwarding to begin with.

Thank you so much @isontheline for your purchase and support about WebSSH 🙏

Agent Forwarding could be insecure in some situations.

Does the "bastion" could be used in your case?

• Does WebSSH support SSH Agent Forwarding? If no, are there any plans to? #463
• Tunnel : Proxy Jump Host : VPN-Over-SSH #266

Agreed about the possible insecurity in certain settings. I use it to SSH into a toy project raspberry pi which is otherwise network segmented off.

Anyways, there is another iOS SSH app, Shelly which is comparable to WebSSH but also support SSH Agent forwarding, so right now I'm set to be able to sudo off my iPhone. I'll go ahead and close this ticket out.
