Ingest GeoIP database APIs

[yuliacech]

The types for the GeoIP APIs are currently not complete in the specification:

• Get geoip database configuration API docs
  The response of the API is not specified, it should be something like

{
  databases: {
    id: string;
    version: number;
    modified_date_millis: number;
    database: {
      name: string;
      maxmind: {
        account_id: string;
      };
    };
  }[]
}

• Create or update geoip database configuration API docs
  The specification doesn't have the correct parameters for request body, so it's not possible to pass the body object to the js client, should be something like

{
    name: string,
    maxmind: {
      account_id: string,
    },
  }

• Delete geoip database configuration API docs
  The specification doesn't have the correct parameters for the request, should be

{
  id: string
}
