GeoIP processor disables SSL certificate validation when downloading databases

Summary

### Impact The GeoIP processor in Data Prepper was configured to trust all SSL certificates and disable hostname verification when downloading GeoIP databases from HTTP URLs, making downloads vulnerable to man-in-the-middle attacks. The GeoIP processor included a custom SSL implementation that completely bypassed certificate validation when downloading GeoIP databases from external sources. The `initiateSSL()` method incorrectly implemented an approach for trusting all certificates. Specifically it: * Accepted all SSL certificates without validation * Disabled server certificate verification * Disabled client certificate verification * Disabled hostname verification This configuration made database downloads vulnerable to man-in-the-middle attacks, potentially allowing attackers to serve malicious GeoIP databases that could compromise the integrity of geolocation data processing. ### Patches Data Prepper 2.12.2 contains a fix for this issue. ### Workarounds If upgrading is not immediately possible: * Use local GeoIP database files instead of downloading from HTTP URLs * Ensure database downloads occur only over trusted networks
