Problem:
Currently harvester installer does not initialise on arm instances on equinix metal.
The original arm implementation skipped the serial console /dev/ttyAMA0 in favour of non serial terminals exposed such as /dev/tty1 exposed on the ampere hosts.
Arm hosts in equinix metal only expose /dev/ttyAMA0 via serial-over-ssh. Since there is no alternate terminal exposed the installer does not start.
Solution:
The PR introduces a minor change to setup-installer script to favour non /dev/ttyAMA0 terminals if one is present such as on Ampere hosts, and failover to /dev/ttyAMA0 if that is the only option.
