1. What is the problem?
In tricircle, some files use oslo_log, while others use logging. The
oslo.log(logging) configuration library provides standardized
configuration for all openstack projects. I think different files in
tricircle should use a same logging module and it's better to use
2. What is the solution to the problem?
Replace logging module with oslo_log.
3. What the features need to be implemented to the Tricircle to realize
No new features
