   ## What is the purpose of the pull request
   Add support ByteArrayDeserializer in AvroKafkaSource
   
   
   
   ## Verify this pull request
   
   When the 'value.serializer' of Kafka Avro Producer is 'org.apache.kafka.common.serialization.ByteArraySerializer',Use the following configuration
   
   --source-class org.apache.hudi.utilities.sources.AvroKafkaSource \
   --schemaprovider-class org.apache.hudi.utilities.schema.JdbcbasedSchemaProvider \
   --hoodie-conf "hoodie.deltastreamer.source.kafka.value.deserializer.class=org.apache.kafka.common.serialization.ByteArrayDeserializer"
   
   For now,It will throw an exception:
   java.lang.ClassCastException: [B cannot be cast to org.apache.avro.generic.GenericRecord
   
   After support ByteArrayDeserializer,Use the configuration above，It works properly.And there is no need to provide 'schema.registry.url',For example, we can use the JdbcbasedSchemaProvider to get the sourceSchema
