Add a utility script to turn off/on all the indicator LEDs
the script will set Asserted property of all the D-Bus objects
under /xyz/openbmc_project/led/groups/ to true or false
One usecase: IBM has a requirement to clean start each power-on
operation by clearing all indicator LEDs. This script will be
used in the power-on sequence.
