Deprecate and remove geo_ip2 feature

[rikatz]

GeoIP feature is used to control access to the environment per location/region. While this is a useful feature, we understand that this control should not be made on ingress-nginx.

Additionally, it is not an open feature that can be consumed by anyone and instead needs a license and a third party module.

So the proposal is to remove and deprecate this feature

Are the whitelist annotation https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#whitelist-source-range and the denylist annotation https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#denylist-source-range related .

Some issues in github seemed to hint at users using geoip2 to ascertain SRC ip (or I could be confused so just commenting)
