Description

Flink master supports 0.10/0.11/2.x, with three flink-sql-connector shade jar currently (1.12-snapshot).

As we all know ,kafka client is compatible after 0.10.2.x, so we can use kafka client 2.x to access to brocker server are  0.10/0.11/2.x. 

So we can just use one kafka sql shade jar. 

for this , we should do 2 things

1) refactor to 1 shade jar

2) rename flink-kafka-connector mudules with same qualified name in case of conflicts such as NoSuchMethod or ClassNotFound error
