build a python application, which serve create/update/delete operations of Mediaplan CustomResourceDefinition through kopf lib. On create, if Mediaplan contain not null "spec.schedule" option, then application create an CronJob, else "Job". On update, do the same, if "spec.schedule" is not null, else first delete an existing job (with waiting), then create again. On delete, delete already existing CronJob or Job
