Code Issues Proposed changes

Amend uuid4 hacking rule

Browse Source 
Starting from oslo.utils 3.20.0,
oslo_utils.uuidutils.generate_uuid can return
"uuid.uuid4().hex" string.

So the following rule has been amended
to use "oslo_utils.uuidutils.generate_uuid(dashed=False)"
instead of "uuid.uuid4().hex".

* N357: Use oslo_utils.uuidutils or uuidsentinel
        (in case of test cases) to generate UUID
        instead of uuid4().
