  - lib.sh: Extend wait_for function to catch no resp

    wait_for function should be able to also check for minions that did
    not return or not respond, in addition to the return code.
    To keep it backwards compatible, condition the new check on the max
    attempt number being specified in decimal format (e.g. '10.0' unlike
    old '10').

  - MaaS: Set commission/deploy timeouts via reclass

    Allow end-users to easily change the MaaS commissioning/deploying

    While at it, use arch-specific values and bump deploy timeout on
    AArch64 to 20 minutes instead of 15.

    issues, switch back to:
    - default Xenial kernel (4.4.x) for base image;
    - hwe-16.04 (4.8.x) for VCP image (similar to Mirantis image);
