    For the specified host, this method provide automation testcases the interface to
    the new ffdc collector ../ffdc/ffdc_collector.py via robot variable FFDC_DEFAULT

    variable FFDC_DEFAULT:1, by default use the existing ffdc collection method.
    variable FFDC_DEFAULT:0 use the new ffdc method

    Command examples:
    (1) Legacy ffdc collection
    python3 -m robot -v OPENBMC_HOST:<> -v OPENBMC_USERNAME:<> \
                                        -v OPENBMC_PASSWORD:<> ./tools/myffdc.robot
    (2) New ffdc collection
    python3 -m robot -v OPENBMC_HOST:<> -v OPENBMC_USERNAME:<> \
                        -v OPENBMC_PASSWORD:<> -v FFDC_DEFAULT:0  ./tools/myffdc.robot
