Update netdb when tunneling requests (#314)

Updating netdb on tunneled transactions (e.g., CONNECT requests) is
especially important for origin servers that are only reached via
tunnels. Without updates, requests for such sites may always through a
cache_peer, even if a direct connection to them is much faster.
