Rotate logs

[pablo]

By default coturn rotates log but doesn't compress them and doesn't delete old one.
Log files will grow to take all the disk space after days/weeks.

Maybe add something like this:

turnserver.conf
log-file=/var/log/turnserver/turn.log
pidfile=/var/run/turnserver/turnserver.pid

/etc/logrotate.d/example-app
/var/log/turn/*.log {
    daily
    missingok
    rotate 14
    compress
    delaycompress
    notifempty
    sharedscripts
    postrotate
        /bin/kill -HUP `cat /var/run/turnserver/turnserver.pid 2>/dev/null` 2> /dev/null || true
    endscript
}
