This bug impacts mitaka and newton branches only; the code was
refactored @ ocata and now does the right thing with regards to building
the entire dict of network data.

Bug description:
  RELEASE: nova-compute-lxd 13.3.0-0ubuntu1

  DESCRIPTION:

  In config.py the network_devices object should be returned after the
  'for vifaddr in network_info:' loop to ensure the network_devices
  object includes all network devices.

  CURRENT CODE (annotated area of interest with >>>>):

      def create_network(self, instance_name, instance, network_info):
          """Create the LXD container network on the host

          :param instance_name: nova instance name
          :param instance: nova instance object
          :param network_info: instance network configuration object
          :return:network configuration dictionary
          """
          LOG.debug('create_network called for instance', instance=instance)
          try:
              network_devices = {}
              if not network_info:
                  return
              for vifaddr in network_info:
                  cfg = self.vif_driver.get_config(instance, vifaddr)
                  key = str(cfg['bridge'])
                  network_devices[key] = {'nictype': 'bridged', 'hwaddr': str(cfg['mac_address']), 'parent': key, 'type': 'nic'}
                  host_device = self.vif_driver.get_vif_devname(vifaddr)
                  if host_device:
                      network_devices[key]['host_name'] = host_device
  >>>>            return network_devices
          except Exception as ex:
              with excutils.save_and_reraise_exception():
                  LOG.error(
                      _LE('Fail to configure network for %(instance)s: %(ex)s'),
                      {'instance': instance_name, 'ex': ex}, instance=instance)
