Optionally run the dashboard on serial console

[josephglanville]

Feature Request

Be able to configure Talos to spawn the dashboard on serial consoles like /dev/ttyS0

Description

In some environments it can be desirable to administer machines without use of a VGA console at all, or on machines that have iKVMs that aren't very user friendly utilising Serial over LAN can be much more ergonomic.

I used a privileged pod (with a bunch of hostPath mounts...) to see if the dashboard works well on serial already and it does!

With this script I was able to launch the dashboard and then interact with it via Serial over LAN:

#!/bin/sh

stty -F /dev/ttyS1 raw -echo -ixon speed 115200
exec setsid sh -c 'exec </dev/ttyS1 >/dev/ttyS1 2>&1 /hostfs/sbin/dashboard'
