Shouldn't we only do the device_json parsing if --remote-device-file is passed?
No point in doing it if device_json is {}, right?

This blocok is pretty repetitive. Can we make it into a function? (Probably a
local one?) e.g. maybe something like this:

def maybe_assign_and_log_override(attr, arg, desc):
  if attr:
    if attr and attr != arg:
      logging.info('Overriding %s from %s to %s', desc, attr, arg)
    attr = arg

maybe_assign_and_log_override(self._api_address, args.api_address,
'api_address')
