bufferevent: move conn_address out from http into bufferevent In http the only case when when we could store it is when we already connected, *but* if we are doing request using domain name, then we need to do request to nameserver to get IP address, and this is handled by bufferevent. So when we have IP address (from nameserver) and don't have connection to this IP address, we could already cache it to avoid extra DNS requests (since UDP is slow), and we can't do this from http layer, only from bufferevent.
