[ZEPPELIN-2211 Too many WARN logs: "Couldn't get interpreter editor setting'
### What is this PR for?
every time we insert invalid backend magic (e.g `sparc`),
`InterpreterSettingManager` throws WARN log.
I changed the log level to debug because
- WARN level should not be used for this kind of situation.
- It's not useful for users. So info level is not proper as well.
I attached a screenshot.
### What type of PR is it?
[Improvement]
### Todos
NONE
### What is the Jira issue?
[ZEPPELIN-2211](https://issues.apache.org/jira/browse/ZEPPELIN-2211)
### How should this be tested?
- Insert invalid magic in your paragraph. For example `sparc` or `marcdown`
### Screenshots (if appropriate)
### Questions:
* Does the licenses files need update? - NO
* Is there breaking changes for older versions? - NO
* Does this needs documentation? - NO
