Description of problem:
When deploying the overcloud, the following is dumped to the console after the deployment is ready:

No handlers could be found for logger "oslo_config.cfg"


Version-Release number of selected component (if applicable):
python-tripleoclient-0.0.11-5.el7ost.noarch


How reproducible:
100%


Steps to Reproduce:
1. Deploy an overcloud. I deployed with 3 controllers and 3 computes on bare metals, but it should probably be reproducible in any deployment.


Actual results:
No handlers could be found for logger "oslo_config.cfg"


Additional info:
The error seems to be harmless, the deployment works.
