Code Issues Proposed changes

Add bonding configuration fields to portgroups 

This change:

* adds mode and properties fields to the portgroup objects and
  describes the changes to nova needed to use them;
* makes portgroup.address field not mandatory;
* brings some updates to CLI & OSC CLI;
* makes this spec dependent on attach/detach interfaces
  work;
* contains some minor cosmetic changes for more readability.

The 'address' field represents the MAC address for bonded NICs of the bare The ``address`` field represents the MAC address for bonded NICs of the bare
metal server. The 'extra' field can be used to hold any additional information metal server. It is optional, as its value is highly dependent on the instance
OS. In case of using ironic through nova, the ``address`` gets populated by
whatever value is generated by neutron for the VIF's address representing this
portgroup, if there is one. This happens during every VIF attach call.
In case of standalone mode, it can be always ``None``, as it should be
configured on the instance through the configdrive.
The ``mode`` field is used to specify the bond mode. If not provided in the
portgroup creation request, its default value is determined by the
``[DEFAULT]default_portgroup_mode`` configuration option, which in turn has a
default value of ``active-backup``. For a portgroup that was created in an
older API version, this configuration value will be used as the value for that
portgroup's mode. ``active-backup`` is chosen as the default because this mode
does not require any additional configuration on the switch side.
The ``properties`` field is a dictionary that can contain any parameters
needed to configure the portgroup.
For additional information about ``mode`` and ``properties`` fields' contents,
see `linux kernel bonding documentation <https://www.kernel.org/doc/Documentation/networking/bonding.txt>`_.

Nova driver impact Nova driver impact
------------------ ------------------
There will be changes necessary to the Nova driver. Proposed changes are: As this work depends on the attach/detach interface work [2]_, the only thing
that needs to be changed to fully support portgroups is configdrive
generation.
* To enable the mapping between Neutron ports and Ironic ports and Nova will call into ironic to get the list of ports of each portgroup that has
portgroups. a VIF associated with it, along with portgroup ``mode`` and ``properties``
fields (see `Data model impact`_ section), and update the network metadata
The Ironic Nova driver has methods ``macs_for_instance``, with the needed information. When the contents of the ``properties``
``dhcp_options_for_instance``, ``extra_options_for_instance`` and dictionary gets passed to the config drive builder in nova, we will ensure
``plug_vifs``. Currently Nova puts a network on one port at random - see that ``bond_`` prefix is prepended to all key names, so that these keys are
`ports cannot be mapped to networks not ignored by cloud-init when reading the config drive.
<https://bugs.launchpad.net/ironic/+bug/1405131>`_. This bug has high
priority and the issue is being addressed. Once addressed, these methods
should determine the number of Neutron ports that are
created as well as the mapping between Neutron and Ironic ports. These
methods should be updated to not only account for Ironic ports but also
Ironic portgroups. The selection process would be:
* Select all Ironic ports that do not belong to Ironic portgroups
(possible if the Ironic port list API returns portgroup_uuid as
standard, as suggested in the above section)
* Select all Ironic portgroups
This modified functionality could be implemented using a new config flag in
Nova to allow toggling between the old and the new methods. The flag could
help de-couple the upgrading of Nova and of Ironic.
