"""Generate LUCI Scheduler config file.
This generates the LUCI Scheduler configuration file for ChromeOS builds based
on the chromeos_config contents.
Changes to chromite/config/luci-scheduler.cfg will be autodeployed:
Normal builds are scheduled based on the builder values for
'schedule' and 'triggered_gitiles' in config/
Branched builds are scheduled based on the function
