Enable Neutron by default

This changes the use_neutron configuration option default
value to True. nova-network has been deprecated since Newton
and only runs in a cells v1 configuration now, so it's time
to make Neutron the default configuration for new Nova
deployments.

As far as testing, the unit tests have already been taken
care of for use_neutron=True by default. There are several
functional tests which are converted over to using Neutron
via the fixture in this change. However, the legacy API
samples functional tests were written with nova-network stubs
so it will take some time to convert over to using Neutron
stubs. This patch does not attempt to clean all of those up
and just configures nova-network by default. The remaining
tests will need to be converted to using Neutron in a later
series of changes.

prelude: >
Neutron is now the default configuration for new deployments.
upgrade:
- |
The nova-network service was deprecated in the 14.0.0 Newton release. In
the 15.0.0 Ocata release, nova-network will only work in a Cells v1
deployment. The Neutron networking service is now the default configuration
for new deployments based on the ``use_neutron`` configuration option.
