features:
- The public functions of ``neutron.db._model_query`` are now available in
``neutron_lib.db.model_query`` with the same name. While these modules can
be used, forward looking projects should start moving to versioned objects
and after which point we can remove this module.
- A new fixture named ``DBQueryHooksFixture`` is provided for testing
purposes allowing consumers to patch-out the model_query filter hooks.
- The ``make_weak_ref`` and ``resolve_ref`` functions from neutron are now
available in ``neutron_lib.utils.helpers``.
- The ``TenantIdProjectIdFilterConflict`` exception is now available in
``neutron_lib.exceptions``.
- The ``neutron.objects.utils`` module is now available in
``neutron_lib.objects.utils``.
