Tests error out when running tests with --debug after oslo.log graduation

[Ian Cordasco]

If you want to debug into the tests, you might do "./run_tests.sh --debug -V glance.tests.unit.v1.test_api.TestGlanceAPI"

This translated to "python -m testtools.run glance.tests.unit.v1.test_api.TestGlanceAPI" which errors out because we attempt to set CONF.debug but the debug option hasn't been registered. This is registered by oslo.log and when using testtools.run, it seems to not be registered (probably because of how testtools imports tests). This prevents tests from running properly and from debugging into them.

    Register oslo.log's config options in tests

    When running tests with testr oslo.log's config options are always
    registered even if you're only running one test. When you wish to debug
    into your tests and use python -m testtools.run these options will not
    be registered.
