We've observed a kafka cluster that attempts to negotiate communication using TLS 1.3 but then fails. This requires us to pin the max version used to TLS 1.2. Currently we're doing that via a monkey patch module prepended onto
Kafka::SslContextbut we'd prefer to have an argument to configure this directly.
