a simple debezium integration test (apache#3154)
### Motivation create a simple debezium integration test. In this test, it start a Debezium MySQL Container based on "debezium/example-mysql:0.8", then use debezium source connector to binlog from MySQL, and store the debezium output into Pulsar. It verify the consumer readout message number is as expected. ### Modifications create a simple debezium integration test. ### Result this test passed.
