  switch to using socket.gethostname() for the name of neutron agents;
  this has the unfortunate side effect with the l3-agent that all router
  services are no longer scheduled on an active agent, resulting in
  floating ip and access outages.

  Looks like this will effect upgrades from grizzly->havana as well:
