unit test and functional test failures with oslo.db 12.1.0

[Lajos Katona]

With the release of oslo.db 12.1.0 some db operations related tests are still unstable:

networking_odl.tests.unit.db.test_db.DbTestCase.test_get_oldest_pending_row_when_dep_completed

And 2 l2gw related functional tests are also failing:
networking_odl.tests.functional.test_l2gateway.TestL2gatewayV2Driver.test_l2gateway_connection_create_delete
networking_odl.tests.functional.test_l2gateway.TestL2gatewayV2Driver.test_l2gateway_delete

More investigation is necessary why these are failing
