Add ServerAliveInterval-like capability to NetBird SSH

[mrbluecoat]

Is your feature request related to a problem? Please describe.
If you netbird ssh into a remote server and run the reboot command your terminal hangs

Describe the solution you'd like
It would be nice if the terminal automatically detects the remote server is no longer active and disconnects cleanly rather than having to manually close the terminal.

Describe alternatives you've considered
The ideas at https://unix.stackexchange.com/q/58271 didn't seem to work with NetBird SSH but -o "ServerAliveInterval 2" recommendation sounds like the right fit if you could add that functionality to your custom SSH process.
