feature request: ability change default log path

Description of problem:

Default log path - /var/log/messages. I can route logs in syslogd with log prefix daemon.info, but also this use sshd, and I cannot toute only ocserv logs. Maybe add ability like in haproxy change this index log (like local0 in haproxy log settings) or add in config option like log-file? Also maybe needed occtl ability to rotate options for logrotate. Thanks!

Version of ocserv used:

1.4.0
