Extract encoding part of KafkaStreamWriter to transformer component

[kevinwallimann]

KafkaStreamWriter should not be dependent on Abris (confluent and Avro)
Thus, the encoding part should be extracted to a preceding transformer component

A new transformer should be created, e.g. za.co.absa.hyperdrive.ingestor.implementation.transformer.avro.ConfluentAvroEncoderTransformer

Breaking changes
Configuration properties will need to be adjusted

How to migrate Hyperdrive-Trigger

1. Replace

"component.writer

"component.transformer.id.2=confluent.avro.encoder", "component.transformer.class.confluent.avro.encoder=za.co.absa.hyperdrive.ingestor.implementation.transformer.avro.ConfluentAvroEncoderTransformer",
"component.writer

2. Replace

writer.kafka.schema

with

transformer.confluent.avro.encoder.schema

3. Replace

writer.kafka.value

with

transformer.confluent.avro.encoder.value

4. Replace

writer.kafka.produce.keys

with

transformer.confluent.avro.encoder.produce.keys

5. Replace

writer.kafka.key

with

transformer.confluent.avro.encoder.key

6. Replace

writer.kafka.option

with

transformer.confluent.avro.encoder.option
