Thanks for doing this Anishek. My comments
Kafka spout should declare the stream id in output declaration.
```
declarer.declare(streamID, _spoutConfig.scheme.getOutputFields()
```
I would prefer the streamID to come from the scheme. More than often the
stream on which data is to be sent to, depends on the input data. Since scheme
knows about the data, it can also determine the stream. This makes more sense
when you think of multiple output streams from same spout. The only downside I
see is that the scheme interface will change and that might translate into
compatibility issues. Nonetheless this PR is a good start.
