AhyoungRyu 7b00dffd98 [ZEPPELIN-982] Improve interpreter completion API ... ### What is this PR for? When people implement a new interpreter, they extend [interpreter.java](https://github.com/apache/zeppelin/blob/master/zeppelin-interpreter/src/main/java/org/apache/zeppelin/interpreter/Interpreter.java) as described in [here](https://zeppelin.apache.org/docs/0.6.0-SNAPSHOT/development/writingzeppelininterpreter.html). Among the several methods in [interpreter.java](https://github.com/apache/zeppelin/blob/master/zeppelin-interpreter/src/main/java/org/apache/zeppelin/interpreter/Interpreter.java), [completion API](https://github.com/apache/zeppelin/blob/master/zeppelin-interpreter/src/main/java/org/apache/zeppelin/interpreter/Interpreter.java#L109) enables auto-completion. However this API is too simple compared to other project's auto-completion and hard to add more at the moment. So for the aspect of further expansion, it would be better to separate and restructure this API before the this release( 0.6.0 ). ### What type of PR is it? Improvement ### Todos * [x] - Create new structure : `InterpreterCompletion` in `RemoteInterpreterService.thrift` and regenerate `zeppelin-interpreter/src/main/java/org/apache/zeppelin/interpreter/thrift/*` files * [x] - Change all existing `List<String> completion` -> `List<InterpreterCompletion> completion` * [x] - Change `paragraph.controller.js` to point real `name` and `value` ### What is the Jira issue? [ZEPPELIN-982](https://issues.apache.org/jira/browse/ZEPPELIN-982) ### How should this be tested? Since this improvement is just API change, it should work same as before. So after applying this patch, and check whether auto-completion works well or not. Use `. + ctrl` for auto-completion. For example, ``` %spark sc.version ``` When after typing `sc.` and pushing `. + ctrl` down, `version` should be shown in the auto-completion list. ### Screenshots (if appropriate)  ### Questions: * Does the licenses files need update? No * Is there breaking changes for older versions? No * Does this needs documentation?
