JobSchedulerRotateLog rotates scheduler.log

Current Situation

• Today job JobSchedulerRotateLog deletes the content of scheduler.log by default.

Desired Behavior

• An option is required for the job to save the old content of the scheduler.log and store it in a file scheduler_old.log
• The main logs should be compressed to a file corresponding to the pattern
  scheduler.log-[yyyy-mm-dd-hhMMss].[schedulerId].log.gz
• This new behaviour is the default behaviour.
• The default parameter for file_age ist 72:00:00 (3 days)
