Read nginx request user ip from ELB X-Forwarded-For
Read nginx request user ip from ELB X-Forwarded-For

Setting real_ip_header defines the request header field whose value
will be used to replace the client address. `set_real_ip_from`
limits the trusted addresses to the default VPC CIDR, so that
if nginx instances are made directly accessible it still wouldn't
be possible to spoof the user IP.
