[Spark-14300][Docs][MLLIB]Scala MLlib examples code merge and clean up
## What changes were proposed in this pull request?
https://issues.apache.org/jira/browse/SPARK-14300
Duplicated code found in scala/examples/mllib, below all deleted in this PR:
- DecisionTreeRunner.scala
- DenseGaussianMixture.scala
- DenseKMeans.scala
- GradientBoostedTreesRunner.scala
- LDAExample.scala
- LinearRegression.scala
- SparseNaiveBayes.scala
- StreamingLinearRegression.scala
- StreamingLogisticRegression.scala
- TallSkinnyPCA.scala
- TallSkinnySVD.scala
Unsure code duplications (need doube check), below two deleted:
- Correlations.scala
- FPGrowthExample.scala
## delete reasons:
#### delete: mllib/DecisionTreeRunner.scala
- duplicate of scala/examples/ml/DecisionTreeExample.scala
- DecisionTreeRunner is referenced in
"milib/GradientBoostedTreesRunner.scalaâ, so delete
GradientBoostedTreesRunner.scala
#### delete: mllib/GradientBoostedTreesRunner.scala
- it referencing above DecisionTreeRunner class
- not being referenced
#### delete: mllib/DenseGaussianMixture.scala
- duplicate of mllib/GaussianMixtureExample
#### delete: mllib/DenseKMeans.scala
- duplicate of mllib/KMeansExample
#### delete: mllib/LDAExample.scala
- duplicate of ml/KMeansExample
#### delete: mllib/LinearRegression.scala
- duplicate of mllib/LinearRegressionWithSGDExample
#### delete: mllib/SparseNaiveBayes.scala
- duplicate of mllib/NaiveBayesExample
#### delete: mllib/StreamingLinearRegression.scala
- duplicate of mllib/StreamingLinearRegressionExample
#### delete: mllib/StreamingLogisticRegression.scala
- never being used or referenced
#### delete: mllib/TallSkinnyPCA.scala
- never being used or referenced
#### delete: mllib/TallSkinnySVD.scala
- never being used or referenced
When merging and cleaning those code, be sure not disturb the previous
example on and off blocks.
