Ok, this is that. If we spcify clientcert=no-verify other than for
"cert" authentication, server complains as the following at startup.

And, cert clientcert=verifry-ca (and no-verify) is correctly rejected.

I once I thought that the deprecation message should e WARNING but
later I changed my mind to change it to LOG unifying to surrounding
setting error messages.
