Consider open data alternative to Geoip db

[pombredanne]

@etix you may want to look at this compatible and open data geoip DB released and maintained by the CIRCL in Luxembourg https://cra.circl.lu/opendata/geo-open/mmdb-country/ by @adulau and team. See also https://github.com/adulau/mmdb-server

Patches welcome.

Some questions I had while looking at the links:

• How does it compare to geoip in general?
• How does it compare for the mirrorbits use case?
• Is there a geoipupdate compatible command or docker image?
