DJ Mountney 860785f007 Make Rack::Request use our trusted proxies when filtering IP addresses
This allows us to control the trusted proxies while deployed in a private network. Normally Rack::Request will trust all private IPs as trusted proxies, which can caue 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.

# Override Rack::Request to make use of the same list of trusted_proxies
# as the ActionDispatch::Request object. This is necessary for libraries
# like rack_attack where they don't use ActionDispatch, and we want them
# to block/throttle requests on private networks.
# Rack Attack specific issue: https://github.com/kickstarter/rack-attack/issues/145
