Link Rdkafka with Bundled SASL

Why it matters

This feature allows ClickHouse to use SASL SCRAM authentication when connecting to Kafka using the bundled librdkafka library. It enhances security by supporting SASL SCRAM mechanisms for Kafka authentication, which is crucial for environments requiring secure communication.

How to use it

Users can enable SASL SCRAM authentication in Kafka integrations by configuring the appropriate SASL parameters in the Kafka consumer or producer settings. This is automatically supported once ClickHouse is built with the updated bundled librdkafka linking SASL support.
