[SPARK-5372][Streaming] Change the default storage level in window operators
The default storage level in window operators is MEMORY_ONLY_SER, which
will lead to unexpected behavior when memory is not enough. Besides for the
reason of aligning this to the storage level of input DStream, here I'd change
the storage level to MEMORY_AND_DISK_SER.
