[ZEPPELIN-1746] Flaky test: PySparkInterpreterTest
### What is this PR for?
PySparkInterpreter (and PySparkInterpreterMatplotlibTest,
SparkInterpreterTest, SparkSqlInterpreterTest) test does not terminate
SparkInterpreter after test end.
In the beginning, keeping SparkInterpreter alive was designed to prevent
create/destroy SparkInterpreter multiple times in various tests, because it
takes some time.
However, that is somehow misbehaving and getting problems like
1. starting another SparkInterpreter before one SparkInterpreter terminates
2. Does not finish PySparkInterpreter process explicitly cause py4j client
somehow creates a lot of connection attempt, that consumes all capacity of
systems port open, and make next SparkInterpreter start fail.
This PR terminates SparkInterpreter after test class finishes, to prevent
above behavior.
### What type of PR is it?

### What is the Jira issue?
