[FLINK-9610] [flink-connector-kafka-base] Add Kafka Partitioner that uses
the hash of the provided key.
## What is the purpose of the change
Add the simple feature of being able to route records into Kafka using a
key based partitioning.
## Brief change log
- Added the FlinkKeyHashPartitioner class with some tests.
## Verifying this change
This change added tests and can be verified as follows:
- Use this instead of the FlinkFixedPartitioner while instantiating the
FlinkKafkaProducer. Also add an KeyedSerializationSchema implementation that
returns the right key that is to be used.
