    Fixed functional iptables firewall tests for newer kernels

    Iptables functional tests fail on Xenial and other newer kernels if
    br_netfilter kernel module is not loaded, in which case sysctl knobs to
    enable bridge firewalling are not available, and attempt to set them
    with _enable_netfilter_for_bridges fails.

    We should load the kernel module before running those tests. Luckily,
    devstack has a function for just that (plus more).
