    Fix noVNC console access for an IPv6 setup

    Following a recent change in websocket proxy code
    (commit: fdb73a2d445971c6158a80692c6f74094fd4193a),
    novnc console access is not working for IPv6 addresses.
    This patch fixes the issue by taking into account the way
    IPv6 urls are constructed and parsing them accordingly.
