Create a file with openmetrics values, so that it be exporter along node-exporter metrics.
=> script runs every 12h to report the status of apt packages to upgrade writes it in /var/lib/node_exporter/apt_info.prom
which is ingested by prometheus when calling node-exporter.
The metrics are used by a grafana dashboard available here : https://grafana.com/grafana/dashboards/23777-apt-ugrades/
