> Add require for one-based indices in loadLibSVMFile
> Customers frequently use zero-based indices in their LIBSVM files. No warnings or errors from Spark will be reported during their computation afterwards, and usually it will lead to wired result for many algorithms (like GBDT).
> add a quick check.
