The goal of this patch is to make the Neutron code compliant with SQLAlchemy 2.0. All SQL transactions must be executed inside an explicit writer/reader context. SQLAlchemy no longer will create an implicit transaction if the session has no active transaction. A warning message, only available in debug mode, is added. When an ORM session calls "do_orm_execute", if there is no active transaction, a warning message with a traceback will be logged to help to debug the regression introduced.
