    Add functional test for deleting BFV server with old attach flow

    When creating a new instance and deleting it before it gets scheduled
    with the old attachment flow (reserve_volume), the block device mappings
    are not persisted to database which means that the clean up fails
    because it tries to lookup attachment_id which cannot be lazy loaded.

    This patch adds a (failing) functional test to check for this issue
    which will be addressed in a follow-up patch.
