[ZEPPELIN-1832] Fixed a bug in zombie process when Zeppelin stopped.
### What is this PR for?
When Zeppelin stops, there is a problem.
Sometimes this happens to the test as well.
It is related to releasing the resources of the remote remote interpreter,
and its order has been modified.
### What type of PR is it?
Bug Fix
### What is the Jira issue?
https://issues.apache.org/jira/browse/ZEPPELIN-1832
### How should this be tested?
1. Zeppelin start
2. run paragraph for interpreter (for example, %spark println("Hello world")
3. Zeppelin stop
4. check to zombie process
```
#jps
```
When Zeppelin exits, the RemoteInterpreter process should not exist.
