This should make peer disconnection easier to debug.
In testing, due to other patches, I managed to flood the send queue with messages and cause us not to be able to send pings, thus getting a peer disconnected for ping timeout. To my surprise, this also force-closed all of my channels with that peeer. Obviously a ping timeout does not indicate that no future connection with said peer will be possible, and we shouldn't be force-closing channels as a result. This also logs when a peer is disconnected to ping timeout to make debug easier.
