    print endpoints using new keystoneauth catalog object

    cinderclient was assuming an identity v2 styled service catalog
    would always be returned (when using `cinder endpoints`).

    keystoneclient would return either a v2 or v3 styled catalog,
    whereas keystoneauth abstracts out the differences and handles
    them internally. the result is that there is no need to look
    for specific ['serviceCatalog'] or ['catalog'] keys in the
    dictionary returned from keystoneauth.

    it should be noted that perhaps cinderclient should deprecate
    the ability to list endpoints since that is mostly an identity
    and admin level operation, and likely an artifact from early
    openstack days, it should now be handled by openstackclient.
    further, it's not clear whether the command is meant to list all
    endpoints or just the endpoints in the user's token (which it does
    now).
