Bug description:
  When instance-monitor sends a notification that an instance is down it
  uses the bare hostname which will result in a host not found error
  being returned by the masakari api service. The code that sends
  notifications of instances being down will always return the bare
  hostname ( https://github.com/openstack/masakari-
  monitors/blob/master/masakarimonitors/instancemonitor/libvirt_handler/eventfilter.py#L48
  ).

  Example of error:
