    Adding networking rules to vm's on compute service startup

    Fixes bug 1027105

    Restarting nova-compute resulted in a new empty iptables chain
    "nova-compute-FORWARD" being create. This commit adds a single
    call to plug_vifs which ensures the appropriate filters (and
    bridge) are present on service startup.
