This PR implements the following posture checks: * Agent minimum version allowed * OS minimum version allowed * Geo-location based on connection IP For the geo-based location, we rely on GeoLite2 databases which are free IP geolocation databases. MaxMind was tested and we provide a script that easily allows to download of all necessary files, see infrastructure_files/download-geolite2.sh. The OpenAPI spec should extensively cover the life cycle of current version posture checks.
