  - p/fuel: network: public: Use arm-virtual2 POD cfg

    FIXME: This should be converted into a dynamic configuration read
    from the universal POD descriptor in securedlab, once that is ready.

    Until then, just align the public network configuration used by the
    virtual POD with the Enea lab configuration specific to arm-virtual2
    (i.e. public network on 10.0.9.0/24).

    NOTE: Replace the gateway at 10.16.0.1 (now 10.0.9.1) with the same
    IP address as our lab's gateway (10.0.9.254), to keep both possible
    network layouts in sync (using all virtual networks created via
    virsh, respectively our lab's static config).
    This will ensure deploys continue to work in both enviroments.

    Also, since our gateway resides at 10.0.9.254, trim the DHCP pool
    range for the public network to not include that address.

    To pass bridge information from CI, Fuel@OPNFV deploy scripts need
    some small adjustments as well.

    While at it, rebase our patches on top of latest Fuel@OPNFV changes.
