    [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.
