[MLLIB] SPARK-5912 Programming guide for feature selection
Added description of ChiSqSelector and few words about feature selection in
general. I could add a code example, however it would not look reasonable in
the absence of feature discretizer or a dataset in the `data` folder that has
redundant features.
