KAFKA-13761: KafkaLog4jAppender deadlocks when idempotence is enabled (#11939) 
When a log entry is appended to a Kafka topic using KafkaLog4jAppender, the producer.send operation
may hit a deadlock if the producer network thread also tries to append a log at the same log level.
This issue is triggered when idempotence is enabled for the KafkaLog4jAppender and the producer
tries to acquire the TransactionManager lock.

This is a temporary workaround to avoid deadlocks by disabling idempotence explicitly in
KafkaLog4jAppender.
