2018-03-27 06:16:32.989475 | ubuntu-xenial | DuplicateOptError: duplicate option: polling_interval

It happens because test runner imports two different modules with the
same option defined. This is a problem now that oslo.config tracks
location of option definitions and consider it a conflict if the same
option is declared in different locations. (The trigger is
