This fails when
nova.tests.functional.api.openstack.placement.test_placement_api
.resource-class-in-use_create_a_resource_class.test_request fails with:

testtools.matchers._impl.MismatchError: '204' not in ['201']

So the PUT is expecting a 201 but it's getting a 204, and then the
DELETE fails with a 404 when it's expecting a 204.

Looks like the failures would correlate with this change being merged on
7/23:
