OpenStack Compute (nova)

Use Neutron by default

Registered by Matt Riedemann

This is a specless blueprint to track the work to change the default value on the CONF.use_neutron option to True. That change itself is trivial, but there is a ton of impact to unit tests by doing that as the tests were mostly written with nova-network in mind, or at least just worked that way, especially with the global network API stub code all over the tests which stubs out nova-network API.

The process to work through this is to basically set CONF.use_neutron=True by default but don't commit that, and run the tests, then focus on a specific set of tests or test module and convert those one at a time to work with use_neutron=True as a default value. If the tests are specifically designed for nova-network, then set self.flags(use_neutron=False).

At the very end of the series we should have a change that sets CONF.use_neutron=True in nova/conf/network.py by default along with a release note for the upgrade impact.

If we get too close to the end of the release and all of the tests aren't converted yet, we can still set CONF.use_neutron=True by default if we just globally set use_neutron=False in the base test class setUp, but we'd continue to need to work on cleaning up tests as nova-network is deprecated and going away.
