    Make request_spec.spec MediumText

    request_spec.instance_group.members is a list of instance UUIDs. It
    can get so long that it overflows its TEXT column. This patch changes
    request_spec.spec to MEDIUMTEXT.

    NOTE(artom): Conflicts in
    nova/tests/functional/db/api/test_migrations.py because of backport
    migration renumbering.

    NOTE(mriedem): Since this is a backport, this contains a release
    note not found in the original change on master.
