define Package/prometheus/description
Prometheus, a Cloud Native Computing Foundation project, is a systems and
service monitoring system. It collects metrics from configured targets at given
intervals, evaluates rule expressions, displays the results, and can trigger
alerts if some condition is observed to be true.

Default tsdb path is /srv/prometheus, you might want to edit /etc/config/prometheus
in order to place it on USB storage or external SD card.
