• Auto-restart the HWTA on something went wrong after 10 seconds
• Auto-restart the main app on something went wrong after 10 minutes (as SLI needs for the HWTA and main app to have matched behavior, but we also prefer a power cycle as the means of recovery)

@arsalansufi per the discussion in this thread, can we investigate applying the restart logic at a lower level? I'm not sure exactly what will be reliable to an ESD shock, but I don't think we can count on an app-level approach.

Noting that we didn't end up adding a lower level restart (as in OS/kernel level). We opted to just call sudo reboot from the app (by way of kiosk-browser).

Once we do more testing with that change in place, we can see whether something more is necessary to get through HW testing.
