fix: expect new `created_at` and `updated_at` fields

[infinitewarp]

I believe this should fix the tests that are failing in camayoc as of https://github.com/quipucords/quipucords/pull/2639

Running locally on just the test that fails that PR:

The CI failures above appear not to be related to my change. One of our internal test target servers has mysteriously gone offline, and that caused the test run to fail prematurely.

Nevertheless, I am closing this request because I have decided to change the aforementioned https://github.com/quipucords/quipucords/pull/2639 so that it is an internal-only change that will not add the new fields to any of the responses. We may add these fields to responses in a future "v2" API.
