[FLINK-3994] [ml, tests] Fix flaky KNN integration tests
This PR is related to flaky KNN integration tests. The problem is caused by
sharing `ExecutionEnvironment` between test cases. I'm not sure about exact
reason. This PR makes each test case have own `ExecutionEnvironment`. Tests on
my local machine and my Travis-CI [1] is passed with this PR.
I have some doubt because this is not essential fix for the problem. AFAIK
and @StephanEwen said, sharing `ExecutionEnvironment` should be supported.
Addtionally, `mvn clean verify` has passed without this PR on my local machine.
If there are any other opinions, please leave comment.
