Make Rack::Request use our trusted proxies when filtering IP addresses
## What does this MR do?
This allows us to control the trusted proxies while deployed in a private network.
## Are there points in the code the reviewer needs to double check?
If we want to limit what is impacted, we can do this specifically for the rack_attack request object.
## Why was this MR needed?
Normally Rack::Request will trust all private IPs as trusted proxies, which can cause problems if your users are connection on you network via private IP ranges.
Normally in a rails app this is handled by action_dispatch request, but rack_attack is specifically using the Rack::Request object instead.
