Prometheus OpenVPN exporter has been broken since OpenVPN 2.5.0 changed
the format of the datetime to ISO8601. After submitting an issue to
upstream, the upstream decided to no longer maintain this exporter.
There ver very many conflicts, basically all due to
name -> pname+version. Fortunately, almost everything was auto-resolved
by kdiff3, and for now I just fixed up a couple evaluation problems,
as verified by the tarball job. There might be some fallback to these
conflicts, but I believe it should be minimal.
