  - Blacklist few Rally tests when verifying Airship
    
    Airship doesn't support live migration and resize server.
    It blacklists them even if all other OPNFV installers have always
    supported these capabilities.
    
    They are still listed as mandatory in CNTT then they are kept in
    CNTT RI compliance.
    
    Here are the Rally tests blacklisted here:
      - 'NovaServers.boot_and_live_migrate_server'
      - 'NovaServers.boot_server_attach_created_volume_and_live_migrate'
      - 'NovaServers.boot_server_from_volume_and_live_migrate'
      - 'NovaServers.boot_and_migrate_server'
      - 'NovaServers.resize_server'
