Run this program besides rasdaemon which is configured to write
events to a sqlite3 database.
Whenever scraped by Prometheus, read the values from the database and
present them as Prometheus counters.
Currently it only exports memoory check events. It expoorts all the
attribute of the event as prometheus labels, which is not optimal, because the
label values are potentially unbounded (the address label can have many
different values).
A simplified mode will be added, which does not add those labels, but instead
offers a REST interface to retrieve the details of the events.
