[SPARK-2103][Streaming] Change to ClassTag for KafkaInputDStream and fix
reflection issue
This PR updates previous Manifest for KafkaInputDStream's Decoder to
ClassTag, also fix the problem addressed in
[SPARK-2103](https://issues.apache.org/jira/browse/SPARK-2103).
Previous Java interface cannot actually get the type of Decoder, so when
using this Manifest to reconstruct the decode object will meet reflection
exception.
Also for other two Java interfaces, ClassTag[String] is useless because
calling Scala API will get the right implicit ClassTag.
