Title:
  "Unable to find a system nic" if openstack lists down ports in json
  config

Status in cloud-init:
  Expired

Bug description:
  We see most ppc64el machines fail to acquire network IPs on
  scalingstack with errors like

  ValueError: Unable to find a system nic for {'mtu': 1458, 'type':
  'physical', 'subnets': [{'type': 'dhcp4'}], 'mac_address':
  'fa:16:3e:6d:95:51'}

  
  In those cases, openstack generated two networks, but only one device is actually present in the VM.

  cloud-init must not abort here, but continue configuring the active network device.
