Traceback when neutron does not support port binding extension in admin screen

[Wim De Clercq]

Similar to https://bugs.launchpad.net/horizon/+bug/1477100

In the admin's edit port view, binding:host_id is expected as part of the port object. This gives a traceback when plugins don't use the port binding extension.

    Handle binding__host_id conditionally

    binding__host_id (binding:host_id in the Neutron API) only exists
    when portbinding neutron extension is available. This extension is
    available in almost all cases as Nova depends on the extension,
    but it is better to check the availability in horizon side as
    we do so in other places in horizon.
