[SPARK-13982][SparkR] Fixed features column header
## What changes were proposed in this pull request?
In KMean's predict the output column name of the features was set to
something like this: "vecAssembler_522ba59ea239__output", which is the default
output column name of the "VectorAssembler".
I set a value "features" which is more intuitive and human readable
**Before fix: **
predict(model, training)
DataFrame[Sepal_Length:double, Sepal_Width:double, Petal_Length:double,
Petal_Width:double, **vecAssembler_522ba59ea239__output:**vector,
prediction:int]
**After fix: **
DataFrame[Sepal_Length:double, Sepal_Width:double, Petal_Length:double,
Petal_Width:double, **features:**vector, prediction:int]
## How was this patch tested?
All previous test cases pass!
