[issue29757] The loop in utility `socket.create_connection()` swallows previous errors

As it stands now(b39d4b1c6) it hardly contains any change - just in the case of multiple intermediate errors AND final failure, the exception raised is a bit different.

AFAICS it would be a "change" for 3.7 if my one of the 3 options of my last comment gets implemented.

Any ideas which one to implement?
