GET /extensions returns an empty list

[Dolph Mathews]

As illustrated by http://keystone.openstack.org/adminAPI_curl_examples.html , GET /extensions returns an empty list regardless of the extensions hardcoded into keystone.

    $ curl http://0.0.0.0:35357/extensions

Returns:

    {
        "extensions":{
            "values":[]
        }
    }
