    - remove reclass data from node
    - Force maas in unconfigured state
      - if you will try to run maas - it will automatically start

      - If you will try to wrap and disable imports (formula allow to do it)
        => maas_config step will never pass.
  * Misc:
    - for to use freezed bootstrap.saltstack.com.sh
    - add qemu-packer disk_compression true - require packer 1.10 +
    - decrease mirror image size to 100gb
    - apt_preserve_sources_list - force cloud-init to not re-create sources.list
