Oslo logging doesn't work during IPA functional tests

[Mario Villaplana]

It appears as though oslo logging doesn't work while running ironic-python-agent's functional test suites.

Steps to reproduce:

1. Add a small log message to ironic_python_agent/agent.py's run() method, i.e. LOG.error("Hello world"). This should log as soon as IPA starts up.

2. Run IPA functional tests: tox -efunc

3. Read the output and notice that "Hello world" does not appear anywhere during the test run, or in ostestr log files.

I believe this occurs because a separate process exists to run the agent. When logging in the test runner process (within a test, or during test setup), logging works as expected.

I had a workaround that substitutes the oslo logger with this: https://docs.python.org/2/library/multiprocessing.html#multiprocessing.get_logger

but that requires modification of non-test files. A workaround that does not require modification of actual agent code is required.

I think we'll need to do something like logging fixture here https://github.com/openstack/cinder/blob/master/cinder/tests/fixtures.py to make things work

Moving to wontfix. I don't beleive this is still the case, and also we are unlikely to do additional work on these functional tests.
