trusty-kilo: neutronclient.common.exceptions.ConnectionFailed: Connection to neutron failed: Maximum attempts reached

With neutron-api absent from the deployment (such as what the amulet test does), use of the neutron python api or command line tool throws this: http://paste.ubuntu.com/10867650/

Juju stat: http://paste.ubuntu.com/10867879/

FYI - The same deployment and the same tests pass with trusty-icehouse and trusty-juno.
