login-proxy: If proxy destination is known to be down, fail immediately. We'll use a simple rule: If connection failed or timed out more recently than it succeeded AND there are currently no clients trying to connect to it, fail it. Since the connect isn't failed unless there is at least one client already trying to connect to it, the proxy notices immediately when the server comes back up and then starts serving it again.
