URL: https://github.com/apache/flink/pull/16417
## What is the purpose of the change
Fix FLINK-22969, verify that topic is not null and not an empty string when
creating KafkaSourceFunction and KafkaSinkFunction。
## Brief change log
The KafkaTopicsDescriptor object will be created in the constructor of the
FlinkKafkaConsumerBase class, and I added a check topic in the constructor of
KafkaTopicsDescriptor to see if the topic is empty。
in FlinkKafkaProducer.FlinkKafkaProducer(
String defaultTopic,
KeyedSerializationSchema<IN> keyedSchema,
FlinkKafkaPartitioner<IN> customPartitioner,
KafkaSerializationSchema<IN> kafkaSchema,
Properties producerConfig,
FlinkKafkaProducer.Semantic semantic,
The int kafkaProducersPoolSize) method is added to check whether the
defaultTopic is empty, because all FlinkKafkaProducer constructors will call
this constructor.
