Basic DoS protection

[hugusmaximus]

Hi, I can see there's a "max_connections" parameter that can be configured to limit "maximum number of connections to a worker", anyway, this will not stop a single attacker IP to trivially flood Sozu... is there any way to configure a limit of connections "per source IP"? This is a very basic feature that only stop most naive DoS attacks but it is very powerful protection mechanism. Any plan to implement this?
