`rhizome/host/bin/reboot-host` takes a boot id as an argument and if matches the current boot id, then issues a reboot. Otherwise it prints the current boot id to stdout. This will be used by the control plane in a loop which will send reboot messages to rhizome until we are sure reboot succeeded (i.e boot id changed).
