@mateiz Instead of renaming `run(RDD[Array[Double]])` to `runRaw`, I
removed it completely and updated the example file `JavaKMeans` and the test
file `JavaKMeansSuite`. Since both approaches introduce breaking changes, users
have to either rename `run` to `runRaw` or map `RDD[Array[Double]]` to
`RDD[Vector]` and call `run`. The latter is perhaps what we want. Python API
stays the same.
