[SPARK-12453][STREAMING] Remove explicit dependency on aws-java-sdk

Successfully ran kinesis demo on a live, aws hosted kinesis stream against master and 1.6 branches.  For reasons I don't entirely understand it required a manual merge to 1.5 which I did as shown here: https://github.com/BrianLondon/spark/commit/075c22e89bc99d5e99be21f40e0d72154a1e23a2

The demo ran successfully on the 1.5 branch as well.

According to `mvn dependency:tree` it is still pulling a fairly old version of the aws-java-sdk (1.9.37), but this appears to have fixed the kinesis regression in 1.5.2.
