    Allow custom time constraints to rotate logs

    Time based constraints must prevail over size et al
    constraints applied for logs of containerized services.
    Time based constraints are needed in order to abide
    GDPR requirements.

    Depending on FS type, Linux may not allow system operators
    to access files creation time attribute (see the Birth
    attribute shown as '-' by the stat -c %w command).
    This is work-arouned by alternative strict time-based rules
    defined in the postrotate script, which purges files in
    /var/log/containers and ensures GDPR compliant system
    configuration, limited to the containerized services logs.

    Extended management of life time of journald and /var/log
    files residing on bare metal hosts, should be done in
    follow up patches.
