containerizing syslog is not only for iptables, it also isolates the /dev/kmsg,
/proc/kmsg, syslog(2)... user space tools in container may use this interface
to read/generate syslog.

But I don't know how important/urgent this containerizing syslog work is,
Rui Xiang, can you find an important/popular user space tool which uses this
interfaces to generate kernel syslog?

Thanks
Gao
