Fix migration for sqlalchemy 1.4
This patch fixes a database migration for sqlalchemy 1.4. It also removes some unused functions from that migration. Note: This patch temporarily disables the scenario jobs to allow this gate fix to merge while the tempest test issue is being resolved. A direct follow up patch will re-enable the tests.
