GeoIP-database-contrib isn't installable

[gbp]

Due to deprecation of the GeoLite Legacy databases we can't run CI builds or build Vagrant boxes.

@lizconlan: with some additional digging, it looks like the underlying problem is that during the Jan 7th maintenance window, it looks like MaxMind have gone ahead and removed the v1 files from their site so the packages installer chokes while attempting the download; geoipupdate looks as though it should fetch the v2 files so that's a partial solution

however...
the v2 files are a different format which the geoip gem we rely on does not understand them https://github.com/cjheath/geoip#featuresproblems

we've had problems in the past where the geoip database was out of date and misidentifying users as being in the US (I think what happened was an IP block or so was transferred between ISPs, possibly due to takeovers - e.g. PlusNet - etc) so keeping it up to date is definitely something we need to keep in mind #2520

For a quick fix to get builds working again we could be to switch to geoip-database, this works as the CSV are included in the package

There seems to be some newer GeoIp replacements listed in cjheath/geoip#75 so we should look at migrating to those at some point - possible the one provided by MaxMind once we drop Ruby <2.3 #4541 #4542 #4842

Try to fix in #5229

That's normally my go to gem for geocoding and... TIL it can use MaxMind with local downloaded DB see: https://github.com/alexreisner/geocoder/blob/master/test/unit/lookups/maxmind_local_test.rb evens provides rake tasks for downloading them too.

Looks like a good solution.
