Comment 1 for bug 1517974

For each error, I get the following line:

ResponseError: 412: 'Precondition Failed' (None None) txid=txacbf413d5c3d4fb2903ad-00564f7860

It looks like the tests are expected to fail with a 412 error when allow_versioned_writes = false, based on the following file (at the time of writing, on lines 105-106):

https://review.openstack.org/#/c/134347/44/test/unit/common/middleware/test_versioned_writes.py

Since the tests behave as expected, my course of action is to have functests skip running the tests associated with TestObjectVersioning and TestObjectVersioningUTF8.
