    neutronv2: translate 401 and 404 neutron client errors in show_port

    This translates the PortNotFoundClient and Unauthorized exceptions from
    the neutron client's show_port call into the corresponding nova
    exceptions. This is useful in the case of a compute API calling
    network_api.show_port, e.g. the os-interface API. The compute API
    should expect a NovaException back from the network API rather than a
    NeutronClientException (since the compute API shouldn't know if it's
    talking to nova-network or neutron).

    Long-term we should refactor more of the neutronv2 API code to re-use
    the show_port method since there are several places where
    neutron.show_port is called directly with additional filtering, etc,
    but they potentially also have the same exception translation issues.
