sslutil: move and change warning when cert verification is disabled
A short time ago, validatesocket() didn't know the reasons why
cert verification was disabled. Multiple code paths could lead
to cert verification being disabled. e.g. --insecure and lack
of loaded CAs.
With the recent refactorings to sslutil.py, we now know the reasons
behind security settings. This means we can recognize when the user
requested security be disabled (as opposed to being unable to provide
certificate verification due to lack of CAs).
This patch moves the check for certificate verification being disabled
and changes the wording to distinguish it from other states. The
warning message is purposefully more dangerous sounding in order
to help discourage people from disabling security outright.
We may want to add a URL or hint to this message. I'm going to wait
until additional changes to security defaults before committing to
something.
