Logs still use the old namespace prefix

[Thomas Herve]

If you remove oslo.messaging=INFO from the default log levels, you can see logs like that:

2017-04-20 17:36:01.349 5408 DEBUG oslo.messaging._drivers.impl_rabbit [-] Timed out waiting for RPC response: timed out _raise_timeout /usr/local/lib/python2.7/dist-packages/oslo_messaging/_drivers/impl_rabbit.py:1036

I suspect it has something to do with stevedore, but I haven't been able to check yet.

FTR it comes from here: https://github.com/openstack/oslo.log/blob/master/oslo_log/log.py#L435

Because oslo.messaging mostly uses logging directly, but drivers use oslo.log, we get both namespaces.

It looks like this is intentional behavior: https://github.com/openstack/oslo.log/blob/4819030b40fd0089ad2bade2317c9705c6fa61d9/oslo_log/log.py#L446

I suppose there's some chance for confusion, but I'm not sure it's enough to justify potentially breaking someone's logging config to change this behavior.
