Our current implementation of data builds is not ideal as the data builders are always present and consume resources. With use of kubernetes CronJobs, we can start the data builder containers when the build is supposed to start. Also, with use of pod priorities, we can replace some less important containers at night time with the data builders and we do not need to have extra machines for the data builders ever.
In the scope of this ticket, hsl timetable container builder should be transformed into CronJobs.
Hsl timetable container builder should operate as a CronJob
