Simple exporter to gather simple metrics about files.

Neat, one metric naming suggestion, file_glob_match_number becomes file_glob_matches.

@SuperQ Is there any rule of thumb for gauges as there is _total for counters (mandatory in OpenMetrics IIRC) ?

Should I still hope for integration ?

Thanks, I think this just got lost in time, merging it now.

There's no explicit suffix convention for gauges, so instead of _number, one generally just uses the plural of whatever is being tallied / measured, and that's it.
