Add support for custom routes to containers (snet)

[Matt Thompson]

From https://github.com/rcbops/rpc-openstack/issues/14:

<snip>

In case br-snet is configured at the glance or neutron containers, ansible should add a route to the service net over the eth3 interface (br-snet) like:

/etc/network/interfaces.d/provider_networks.cfg for eth3:
post-up ip route add 1.2.3.0/18 via 172.29.248.1

Currently I would like to have the service network to be configured as mandatory option inside the rpc_user_config.yml and probably the host interface. So we can add

iptables -t nat -A POSTROUTING -s 172.29.248.0/22 -o -j MASQUERADE

to the infra nodes. iptables-persistent shoud be installed in that case too

    Add support for specifying custom static routes

    This change allows you to specify static routes for a given network in
    your openstack_user_config.yml file:

      global_overrides:
        provider_networks:
          - network:
              group_binds:
                - glance_api
                - nova_compute
                - neutron_linuxbridge_agent
              type: "raw"
              container_bridge: "br-snet"
              container_interface: "eth3"
              container_type: "veth"
              ip_from_q: "snet"
              static_routes:
                - cidr: 10.176.0.0/12
                  gateway: 172.29.248.1

    This will result in the following being written to
    /etc/network/interfaces.d/eth3.cfg for the affected containers:

      post-up ip route add 10.176.0.0/12 via 172.29.248.1 || true
