    Avoid imposing alembic 6.0 requirement on all distros

    Related-to: LP 1224666

    Two of the alembic-based migrations use the new 'type_' kwarg in calls
    to op.drop_constraint(), even though the old 'type' form was retained
    for backward compatability:

      https://alembic.readthedocs.org/en/latest/ops.html

      "Changed in version 0.5.0: The type parameter is now named type_.
      The old name type will remain for backwards compatibility."

    To avoid needlessly imposing the alembic 6.0 on distros for which this
    version is not yet packaged, we revert these migrations to use the older
    form.

    The corresponding change to the global requirements is proposed here:
