[SPARK-9030][STREAMING] Add Kinesis.createStream unit tests that actual sends data

[tdas]

Current Kinesis unit tests do not test createStream by sending data. This PR is to add such unit test. Note that this unit will not run by default. It will only run when the relevant environment variables are set.

Thanks @tdas I'm not familiar with Kinesis client APIs. But generally looks good and Jenkins is green. I will add Python tests for the Kinesis Python API after this PR is merged.
