With latest sqlalchemy there is no alter attribute for the Column object
Thus, zun-db-manage upgrade fails with AttributeError. Instead of trying
to use SQLAlchemy for altering Column we should use alembic instead
for the migration
This also fix py3.11 job by replacing libmysqlclient-dev with
libmariadb-dev-compat which is available for both ubuntu and debian.
