docstring: Deletes old raw data based on the options set in the Deletelogs config
  section. This is a scheduled task and will only execute every N days. The number
  of days is determined by the delete_logs_schedule_lowest_interval config option.
  
  If delete_logs_enable is set to 1, old data in the log_visit, log_conversion,
  log_conversion_item and log_link_visit_action tables is deleted. The following
  options can tweak this behavior:
  - delete_logs_older_than: The number of days after which raw data is considered old.
  
  @ToDo: return number of Rows deleted in last run; Display age of "oldest" row to help the user setting
  the day offset;
