- rename all /etc/nut/*.conf.sample to /etc/nut/*.conf
- make conf.d/* init.d/* more clean and openrc-run'ed
- nut-upsmon now dynamically depends on nut-upsd if the MODE parameter in /etc/nut/nut.conf is set to 'standalone' or 'netserver'.
- make a user and group creation in pre-install. I think we need to remove this user/group from alpine-baselayout.
