Log SSL alerts more prominently

When we receive an SSL alert from a server we currently only log a very cryptic OpenSSL error message: OpenSSL: error:0A00042E:SSL routines::tlsv1 alert protocol version:SSL alert number 70 This also enables logging the much more readable SSL error message: Received fatal SSL alert: protocol version which previously needed --verb 8 to be displayed (now verb 3). Also rework the message to be better readable.
