[SPARK-16580][CORE] class Accumulator in package spark is deprecated: use
AccumulatorV2
https://issues.apache.org/jira/browse/SPARK-16580#
## What changes were proposed in this pull request?
When I was working on the R wrapper, I found the compile warn.
```

```
Using `AccumulatorV2` and warnings on "PythonRDD.scala:78" and
"PythonRDD.scala:71" disappeared.
I didn't change `AccumulableParam` or `AccumulatorParam`, since they are
being used in `class LegacyAccumulatorWrapper` of `AccumulatorV2`.
## How was this patch tested?
Tested manually on my laptop.
