Commit 4dc37abc removes the few instances of LOG.audit that
were in Cinder. Given that the plan is to remove LOG.audit messages
from OpenStack, I am adding this hacking check to ensure that such
messages do not sneak their way back into Cinder.
Unit tests are included with this change.

Guidelines for writing new hacking checks
|
|
|
|
- Use only for Cinder specific tests. OpenStack general tests
|
|
should be submitted to the common 'hacking' module.
|
|
- Pick numbers in the range N3xx. Find the current test with
|
|
the highest allocated number and then pick the next value.
|
|
- Keep the test method code in the source file ordered based
|
|
on the N3xx value.
|
|
- List the new rule in the top level HACKING.rst file
|
|
- Add test cases for each new rule to
|
|
cinder/tests/test_hacking.py
