Hey all, This is a trivial one-liner change that it was determined should go through a KIP during the PR review process (see this thread <https://github.com/apache/kafka/pull/14681#discussion_r1378591228> for context). Since the change itself was already reviewed and approved I'm skipping the discussion thread and bringing it to a vote right away, but of course I'm open to feedback and can create a discussion thread if there is need for it.
The change itself is simply adding the `protected` modifier to the ProducerConfig constructor that allows for silencing the config logging. This just brings the ProducerConfig in alignment with the other client configs, all of which already had this constructor as protected.
