    Add 'path' query parameter to console access url

    Starting in noVNC v1.1.0, the token query parameter is no longer
    forwarded via cookie [1]. We must instead use the 'path' query
    parameter to pass the token through to the websocketproxy [2].
    This means that if someone deploys noVNC v1.1.0, VNC consoles will
    break in nova because the code is relying on the cookie functionality
    that v1.1.0 removed.

    This modifies the ConsoleAuthToken.access_url property to include the
    'path' query parameter as part of the returned access_url that the
    client will use to call the console proxy service.

    This change is backward compatible with noVNC < v1.1.0. The 'path' query
    parameter is a long supported feature in noVNC.
