Add support to retrigger LED Update

RetriggerLEDUpdate method added in callback-manager serivce. Used
to re-init the LED state in xyz.openbmc_project.LED.GroupManager.
This can be used by manufacturing revert function to re-init the
LED to the correct state, after any testing.

Tested:
1. Manually updated the LED state and called RetriggerLEDUpdate
method, which re-init the LED status, and set's to the correct one.
