   Introduce built-in connectors for better startup, test, production-debug, 
and etc...
   
   1.datagen source:
   - easy startup/test for streaming job
   - performance testing
   
   2.print sink:
   - easy test for streaming job
   - be very useful in production debugging
   
   3.blackhole sink
   - very useful for high performance testing of Flink
   - I've also run into users trying UDF to output, not sink, so they need this 
sink as well.
