A basic prometheus exporter for version 6

I couldn't find a prometheus exporter that works with the new API (and let me know if you did... because I'll stop :stuck_out_tongue: ), so I started working on one a few days ago. It's not much yet, but it's getting the stats/summary and stats/upstreams data out.

It's python and requires the (apt-gettable) prometheus_client library.

I hope to flesh it out, give it proper command-line options, and whip up a complete dashboard for it.

UPDATE: That was fast... it's fleshed out. Supports the API token (if you're requiring that), port adjustment, and host adjustment (say, to run it remotely). I'm filling out the README and working on a dashboard for this (I have panels made up, but incorporated into other personal dashboards so far).
