[SPARK-5520][MLlib] Make FP-Growth implementation take generic item types
(WIP)
Make FPGrowth.run API take generic item types:
`def run[Item: ClassTag, Basket <: Iterable[Item]](data: RDD[Basket]):
FPGrowthModel[Item]`
so that user can invoke it by run[String, Seq[String]], run[Int, Seq[Int]],
run[Int, List[Int]], etc.
Scala part is done, while java part is still in progress
