History

This change adds the container network MTU option within the container
network LXC config file. This will allow a deployer to set the MTU within
a provider networks entry in openstack_user_config.yml.

Example:

  ....
  provider_networks:
    - network:
        container_bridge: "br-storage"
        container_type: "veth"
        container_interface: "eth2"
        ip_from_q: "storage"
        type: "raw"
        container_mtu: "9000"
        group_binds:
          - glance_api
          - cinder_api
          - cinder_volume
          - nova_compute
          - swift_proxy

This changes gives the deployer the ability to selectively set the mtu as
needed.

The dynamic_inventory.py script has been updated to allow for the MTU entry.

Example file documentation has been added to show how to use this new setting.
