URL: https://github.com/apache/flink-ml/pull/76
## What is the purpose of the change
This PR mainly updates the static `load` method of all Stage `subclasses` to
use `StreamTableEnvironment`.
## Brief change log
- Add helper method `TableUtils::getExecutionEnvironment` to get the
corresponding `StreamExecutionEnvironment` from a `StreamTableEnvironment`.
- Changes the signature of the static `load` method of all `Stage` subclasses
- from `public static T load(StreamExecutionEnvironment env, String path)`
- to public `static T load(StreamTableEnvironment tEnv, String path)`
- Changes the signature of the static `ReadWriteUtils::loadModelData` method
- from `public static <T> DataStream<T>
loadModelData(StreamExecutionEnvironment env, String path,
SimpleStreamFormat<T> modelDecoder)`
- to `public static <T> Table loadModelData(StreamTableEnvironment tEnv,
String path, SimpleStreamFormat<T> modelDecoder)`
- Changes the signature of the static
`KMeansModelData::generateRandomModelData` method
- from `public static DataStream<KMeansModelData>
generateRandomModelData(StreamExecutionEnvironment env, int k, int dim, double
weight, long seed)`
- to `public static Table generateRandomModelData(StreamTableEnvironment
tEnv, int k, int dim, double weight, long seed)`
