    NVP plugin:fix connectivity to fip from internal nw

    The current set of NAT rules configured in the NVP logical router
    prevents instances on an internal network from establishing TCP
    connections with a floating IP associate with an internal port
    on the same Neutron network.

    This patch add a SNAT rule to ensure connections coming from the
    internal network always appear to the port associate with the
    floating IP as coming from the external network.
