FLINK-5976 [tests] Deduplicate Tokenizer in tests
There are some duplicate code like this in flink-test, I think refactor
this will be better.
```
public final class Tokenizer implements FlatMapFunction<String,
Tuple2<String, Integer>> {
@Override
public void flatMap(String value, Collector<Tuple2<String, Integer>>
out) {
// normalize and split the line
String[] tokens = value.toLowerCase().split("\\W+");
// emit the pairs
for (String token : tokens) {
if (token.length() > 0) {
out.collect(new Tuple2<String, Integer>(token,
1));
}
}
}
}
```
