  - 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').
