    Open firewall port 3300 for ceph monitors v2 protocol

    In addition port 6789, open port 3300 too for ceph monitors.
    As per the Ceph documentation:

    "Ceph monitors now bind to IANA-assigned port 3300 (ce4h or 0xce4)
    for the new v2 protocol, while also binding to the old default
    port 6789 for the legacy v1 protocol."
