The oslo library provides database helpers that can be reused across projects. The switch should be transparent to the end user due to support for backwards-compatible configuration, but the new oslo-specific configuration will need to be documented. https://blueprints.launchpad.net/neutron/+spec/oslo-db-support
Ofer - There isn't a need for special testing. If the higher-level neutron tests work, then the db implementation works. This bug is mainly to ensure that the docs are updated to reflect changes to configuration.
There is no user-visible functional change associated with this bug, but the configuration format has been changed in a backwards-compatible way.
