dynamic_inventory.py container_mtu bug

[Bjoern]

While I was adding a new container_mtu setting for one provider network (vxlan), I epexcted that it'll get propagated to the neutron_agents_container. Afterall they are bound to it via the neutron_linuxbridge_agent group. But I noticed that the setting only propagated to the
tunnel_address dict of the compute nodes, as mtu and at the provider_networks.[vxlan] as container_mtu. I had to manually add the mtu item to the neutron_agents container to make it work.

This issue was observed with Newton

    - network:
        container_bridge: "br-vxlan"
        container_type: "veth"
        container_interface: "eth10"
        container_mtu: 9000
        ip_from_q: "tunnel"
        type: "vxlan"
        range: "1:1000"
        net_name: "vxlan"
        group_binds:
          - neutron_linuxbridge_agent

    Update existing container_networks

    We don't update an existing container_network so once you have settings
    set, they will not be changed, even if you change settings.

    This patch ensures that if the existing container_network does not match
    the current provider_network, it will get updated.
