    [docker] Added a new flag to disable default network

    Docker is using 172.17.0.0/16 by default for bridge networking on
    docker0, and this might cause routing problems for operator networks.

    This change introduces docker_disable_default_network to disable the
    bridge networking by putting "bridge: none"[1] to daemon.json

    Bridge networking does not work without iptables, so we set the default
    for docker_disable_default_network to
    docker_disable_default_iptables_rules.

    For better defaults, this feature will be enabled by default in
    Wallaby.
