KIP-85 — Dynamic JAAS configuration for Kafka clients

Accepted Kafka 1.0 Security

Adds a sasl.jaas.config property to Kafka client and broker configs, allowing JAAS login configuration to be specified inline in the Kafka properties file rather than requiring a separate JAAS file. Managing separate JAAS files is cumbersome in containerized and cloud deployments where property-based configuration is standard; also enables different SASL configs per listener without shared JVM state.
