[ZEPPELIN-5070] Improve start/shutdown and signal handling
### What is this PR for?
These PR touch the start and stop procedures of all interpreters.
- improved start script with [shellcheck](https://www.shellcheck.net/)
recommendations
- Use `exec [...]` instead of `eval [..] &`, which means that the Java
interpreter process is not a fork of the shell script
-> no trap handling required in the start script
-> signals land in the JVM
- Correct escaping is done by the start-script
- remove anonymous threads in 'RemoteInterpreterServer.java and give the
thread nice names
- Use TServer's StopTimeoutVal and stopTimeoutUnit for faster shutdown
- remove special K8s shutdown handling
- unregister interpreter during unpredictable shutdown
### What type of PR is it?
- Improvement
### Todos
* [ ] - Task
### What is the Jira issue?
* https://issues.apache.org/jira/browse/ZEPPELIN-5070
### How should this be tested?
* Travis-CI: https://travis-ci.com/github/Reamer/zeppelin/builds/198263926
### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
