[management] Auto update geolite

[benniekiss]

Describe your changes

Introduces automated updates for GeoLite databases, eliminating the need to manually run the download-geolite2.sh script. Key changes include functions to fetch and update database files based on versioned filenames, auto-download logic when outdated files are detected, and a new --disable-geolite-update flag.

By default, this flag is set to true, disabling automatic updates. Users who want to enable auto-updates can do so by setting --disable-geolite-update=false. Additionally, obsolete scripts and reload functions have been removed.

This update simplifies version tracking and ensures database consistency without manual intervention while offering flexibility for self-hosted users.
