[stable/victoria] ddt version incompatibility for victoria branch

[Sam Morrison]

In victoria test-requirements state:

ddt>=1.2.1

However the tests use the code:

cinder/tests/unit/volume/flows/test_create_volume_flow.py:@ddt.ddt(testNameFormat=ddt.TestNameFormat.INDEX_ONLY)

Which is not in ddt 1.2.1

Failures during discovery

--- import errors ---
Failed to import test module: cinder.tests.unit.volume.flows.test_create_volume_flow

    @ddt.ddt(testNameFormat=ddt.TestNameFormat.INDEX_ONLY)
AttributeError: module 'ddt' has no attribute 'TestNameFormat'

This is the version that is in ubuntu focal victoria

This breakage was added in commit 8095a7af801e7b4511bde7e02412bcd6687eb1d1

Not sure the best way to handle this, update the test-reqirements for stable/victoria ?

This is interesting because the current CI for stable/victoria passed because I think it's using the master file test-requirements.txt ( ddt==1.4.1 ) instead of the stable/victoria one [1]. Maybe we can update the version in stable/victoria code. [2]
