Connector is not auto retrying on Indexing Error

When attempting to write to ElasticSearch and an "Indexing record failed" error occurs, the connector dies without any retries. We do not even see the retry log execute.

Kafka Connect Image: confluentinc/cp-kafka-connect:7.1.1 Elastic Search Connector: confluentinc/kafka-connect-elasticsearch:13.0.0 Elastic Search Version: 7.8.0
