[SR-Users] EOL of geoip module.

[Sergey Okhapkin]

Maxmind just announced EOL of legacy geolite databases used by geoip module, 
no updates starting this April. See more at https://blog.maxmind.com/

If you use kamailio's geoip module, I suggest to switch to geoip2 module which 
uses Geolite2 databases and is a plug in replacement for geoip module.
