[FLINK-2984] [ml] Extend libSVM file format support
Currently, FlinkML libSVM file reader cannot read some datasets (such as
splice-site) in libSVM official site. This PR extends libSVM file format to
liblinear equivalent. To avoid re-compiling regex pattern in every line, I
changed the mapper from scala lambda function to `RichFlatMapFunction`.
