sslutil: handle ui.insecureconnections in validator
Right now, web.cacerts=! means one of two things:
1) Use of --insecure
2) No CAs could be found and were loaded (see sslkwargs)
This isn't very obvious and makes changing behavior of these
different scenarios independent of the other impossible.
This patch changes the validator code to explicit handle the
case of --insecure being used.
As the inline comment indicates, there is room to possibly change
messaging and logic here. For now, we are backwards compatible.
