    Add region config to [neutron] in nova.conf

    On multi-region deployments, Nova may talk to the wrong
    neutron endpoint (from the wrong region) if the region
    is unspecified.

    The issue that requires this fix is most apparent when
    doing live migrations, as the Conductor tries to call
    Neutron to perform port bindings.
