This is in a way a follow-up for Ia97d6cf24e554f7b3878dd301ae4e7e10a1c9998 that removed the same in production neutron code to rely on default values inherited from oslo.db. There is no clear need to override those settings in test environment either, so at best it's boilerplate code. Related-Bug: #1682307 Change-Id: Ie2e2dd0659b1cd6d8b8480e2d78d00475ab01b40
