upgrade:
- A new ``use_neutron`` option is introduced which replaces the
obtuse ``network_api_class`` option. This defaults to 'False' to
match existing defaults, however if ``network_api_class`` is set
to the known Neutron value Neutron networking will still be used
as before.
- A new ``use_neutron`` option is introduced for configuring Nova to
use Neutron for its network backend. This replaces the deprecated
``network_api_class`` and ``security_group_api`` options, which are
confusing to use and error prone. The default for this new value
is ``False`` to match existing defaults, however if
``network_api_class`` and/or ``security_group_api`` are set to
known Neutron values, Neutron networking will still be used as
before. Installations are encourged to set this config option soon
after upgrade as the legacy options will be removed by the Newton
release.
