The current helm chart defaults drops logs of any warnings
(and above) for any logger outside of the namespace
of the deployed chart.
This is a problem, as logging could reveal important information for
operators. While this could be done with a value override, there
is no reason to hide warning, errors, or critical information that
are happening in the cycle of the operation of the software
deployed with the helm charts. For example, nothing would get
logged in oslo_service, which is a very important part of running
OpenStack.
This fixes it by logging to stdout all the warnings (and above)
for OpenStack apps.
