[SPARK-3369] [CORE] [STREAMING] Java mapPartitions Iterator->Iterable is
inconsistent with Scala's Iterator->Iterator
Fix Java function API methods for flatMap and mapPartitions to require
producing only an Iterator, not Iterable. Also fix DStream.flatMap to require a
function producing TraversableOnce only, not Traversable.
CC @rxin @pwendell for API change; @tdas since it also touches streaming.
