    console: make unsupported ws scheme in python < 2.7.4

    Due to a bug in python < 2.7.4, urlparse won't parse a query string
    in a URL where the scheme is not recognized:

    http://bugs.python.org/issue9374

    Commit 1dda5ef75a5c141c316639716820b0c37773a9e3 added some tests for
    websocketproxy that uses urlparse to get a token but these don't work
    on python < 2.7.4 since the scheme in the tests is "ws://".

    In the actual code, raise an exception if python < 2.7.4 and an
    unsupported URL scheme is used.

    DocImpact: The "getting-started-with-vnc-proxy" page in the
    "admin-guide-cloud" docs should be updated with a note that the web
    proxy console URLs do not support the websocket protocol scheme (ws://)
    on python versions less than 2.7.4.
