Parse LocalForward from SSH config

[gabrielrussoc]

Even though EternalTerminal supports port forwarding by default, it doesn't understand the LocalForward directive from ssh config:

LocalForward
Specifies that a TCP port on the local machine be
forwarded over the secure channel to the specified host
and port from the remote machine. The first argument
specifies the listener and may be [bind_address:]port or a
Unix domain socket path. The second argument is the
destination and may be host:hostport or a Unix domain
socket path if the remote host supports it.

https://man7.org/linux/man-pages/man5/ssh_config.5.html

This is a very crude implementation that simply parses those configs in a straightforward (and incomplete) way and turns all errors into warnings, just like ssh does by default.
