Make FOSS proxy treat connections with unknown sources more gracefully

Browse source 
When a connection to the proxy using the PROXY protocol (https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt) comes from an IP address that the external load balancer does not recognize, make the source IP 0.0.0.0. This way an appropriate WHOIS quota can be configured for this kind of connections.
