----------------------------------
[~dwysakowicz],
This change will bring the following effects
1) user don't need to know which kafka conector version to add to the
classpath, just put them all ,and the jar is pretty small
2) if there are several kafka cluster with diffirent version, user want to use
one flink access them all conveniently. user just dynamically load the kafka
client version they want .
> flink kafka connector exists same qualified class name, whch will cause
> conflicts when user has all the versions of flink-kafka-connector
