Block countries - Nginx

[Frank Liu]

Since only load balancer sees the client IP, it has to pass that
information to nginx. You need to talk to your LB engineer and depending on
the type of LB, there are different ways to do that. Once the information
is passed to nginx, nginx will expose it as a variable, which can then be
used by the geoip2 module to do the lookup and create country code for you
to use for blocking.
