    Extend VNC port range

    Per the attached bug, if a large number of instances are colocated
    on a single compute node it is possible to exhaust the allowed VNC
    ports. This change extends the range to include 1024 ports, which
    with the default 16x overcommit ratio in Nova means we could handle
    a fully loaded 64 core server. That's _probably_ overkill, but I
    think it makes sense to overshoot a bit on this and ensure nobody
    runs into weird problems because their VNC ports weren't allowed
    through the firewall.
