    Fix FloatingIP Namespace creation in DVR for Late Binding

    DVR has dependency on the portbinding host to determine
    where to start the FloatingIP Namespace when floatingip
    is configured. But when we assign a floatingip to a port
    that is not bound, even though the API will succeed, the
    FloatingIP Namespace will not be created by the Agent and
    so the FloatingIP will not be functional.

    This patch addresses the issue by creating the Namespace
    and configuring the rules when the late binding happens.

    The agent will be requesting the FIP agent gateway port,
    if required and then proceed to configure the FloatingIP
    Namespace.
