    Force GDPR compliance of containers logs

    After purge_after_days, defaults to a 14, forcibly remove
    any rotated and compressed logs of containerized services
    in /var/log/containers. This overrides any related
    containerized logrotate configuration used for
    containerized services.

    Allow to alter rotation interval for log files managed
    via containerized logrotate. Defaults to 'daily'
    and rotate 14 (days).

    Use sharedscripts to clean up files in the postrotate
    script only once.

    Additionally, to enforce GDPR compliance of log files
    in /var/log/containers, put them under logrotate management
    (minsize 1) and always compress. Prohibit the size option
    as it does not honor time-based contstraints required by
    GDPR. Forcibly remove all files but those rotated and
    compressed logs, via the postscript section.
