Backport of 3fad712a91a8a8f6f6f904aff3d895e3b06b24c7 from main.
GEOIP_SETTINGS is removed from the global scope as this prevents
modifications to the settings using @override_settings in tests.
Additional improvements now that we have stable test databases include:
- Made testing more comprehensive and improved coverage
- Patched socket.gethostbyname() for whole test case
- Added testing of non-free GeoIP2 databases
