Spec Lite: Remove sqlalchemy-migrate
Mandatory sections
:project: glance
:problem: The sqlalchemy-migrate library is unmaintained and has been
deprecated in favour of alembic. It is not compatible with sqlalchemy
2.0 and is issuing many warnings suggesting Python 3.10 compatibility
may be in doubt. Glance switched to alembic for new migrations during
the Ocata cycle and no longer needs to carry the old
sqlalchemy-migrate-based migrations.
:solution: Remove the sqlalchemy-migrate-based migrations and related tooling.
:impacts: None. Users coming from a pre-Ocata deployment will need to deploy a
pre-Xena glance before deploying Xena, but that's standard practice
Optional sections -- delete any that don't apply to this spec lite
:timeline: Xena milestone 3
