auth: reduce logging for "GSS-TSIG request but feature not compiled in"

[patrickpoortman]

• Program: auth
• Issue type: Feature request

Short description

Reduce logging output when GSS-TSIG requests are made to auth when the GSS-TSIG feature was not compiled in PowerDNS to prevent unnecessary logging. Or make this log message optional.

Usecase

For each GSS-TSIG request made there is a log entry made at the error level, when it is not part of the compile options.

Two lines above the same. Level should probably be "Debug". I'll make a PR (I am the author iirc).

Actually, this is an auth issue, not a dnsdist issue, I'll edit it a bit.
