Subject: [SPARK-18279][DOC][ML][SPARKR] Add R examples to ML programming
 guide.

## What changes were proposed in this pull request?
Add R examples to ML programming guide for the following algorithms as POC:
* spark.glm
* spark.survreg
* spark.naiveBayes
* spark.kmeans

The four algorithms were added to SparkR since 2.0.0, more docs for algorithms added during 2.1 release cycle will be addressed in a separate follow-up PR.

## How was this patch tested?
This is the screenshots of generated ML programming guide for ```GeneralizedLinearRegression```:

Closes #16136 from yanboliang/spark-18279.
