Zun changes the format of 'addresses' attribute

[hongbin]

The OS::Zun::Container resource has a 'addresses' attribute. This attribute is of format:

  {
      'private': [{
          'version': 4,
          'addr': '10.0.0.12',
          'port': 'ab5c12d8-f414-48a3-b765-8ce34a6714d2'
      }]
  }

With the original format, users can retrieve IP address by:

  {get_attr: [<container>, addresses, private, 0, addr]}

In order to handle the scenario that multiple neutron networks have the same name, Zun switches to use uuid instead:

    {
      <uuid>: [{
          'version': 4,
          'addr': '10.0.0.12',
          'port': 'ab5c12d8-f414-48a3-b765-8ce34a6714d2'
      }]
  }

For users who try to retrieve IP address by name, it will break.

    Extend addresses attribute of Zun container

    The original 'addresses' field is a map from neutron network uuid
    to an address list. For example:

      {'ed5c1b52-01ab-4a89-8b99-00705d9066c6': [..]}

    This commit proposes to extend it to neutron network name. This
    allows the address list to be hashed from uuid or name of a network.

      {'ed5c1b52-01ab-4a89-8b99-00705d9066c6': [...],
       'private': [...]}

    This improvement will make the format of addresses consistent
    between containers and VMs. In addition, it allows retrieving IP
    addresses through either network name or network id. For example:

      {get_attr: [my-container, addresses, private, 0, addr]}

    or

      {get_attr: [my-container, addresses, <uuid>, 0, addr]}

    The first form is more user-friendly and the latter is able to
    resolve ambiguity that two networks have the same name.
