  - Merge "Fix transition states for the BB workflow."
  - Fix transition states for the BB workflow.

    Deleted the versioned flyway file in favor of the repeatable
    one for MacroData. I know deleting a versioned file could mess up
    upgrade but given no release has been done with those new versioned files
    it should be ok and cleaner.

    This is a list of transition states that were added internally at Bell
    when working with the BB workflow and post instantiation.

    Those are to support Rollback and Delete even if the VNF is in the status
    ConfigAssigned, Configure or Configured.
    The missing transition states was causing the Rollback or Delete to fail.
