Bug Description
We have observed in the cloud that instances fail to delete properly and enter into an ERROR state. This appears to happen when many instances are deleted at the same time. Investigation found that regular session passed to Nova instead of the scoped one. I assume it is oslo.db issue because public interface of oslo.db provides only prepared sessionmaker to Nova. Tried to fix it [1], but patch breaks many tests.
