The systemd unit for atop service is changed, so the log file name and
location will be always the same. It also adds the logrotate
configuration to conditionally rotate a log file.
Hardcoded values:
- maximum log file size: 10 MB
- maximum count of files: 10
These values can be easily changed within the
`/etc/logrotate.d/vyos-atop`, no additional configuration is required.
Rotation will be done hourly, if necessary, according to
`/etc/cron.hourly/vyos-logrotate-hourly`.

This change has two benefits:
- rotation strategy control can be done via logrotate, and can be
exposed to CLI now;
- the total size of all logs is now controlled more aggressively, so
the chance to get a situation when atop logs took all the space on a
drive is significantly lower. Also, if this will be necessary, rotation
may be done even each minute what reduces risks related to logs size
even more.
