add logrotate stub

i m trying to move away from cron. so i am using a systemd timer (borrowed from arch)

timer:

[Unit]
Description=Daily rotation of log files

[Timer]
OnCalendar=daily
AccuracySec=12h
Persistent=true

[Install]
WantedBy=multi-user.target

service:

[Unit]
Description=Rotate log files

[Service]
Type=oneshot
ExecStart=/usr/sbin/logrotate /etc/logrotate.conf
Nice=19
IOSchedulingClass=best-effort
IOSchedulingPriority=7
add support for dnf, since fedora has a dnf-makecache.timer running
