ZEPPELIN-2015 Improve parsing logic of livy sql output
### What is this PR for?
This PR is trying to resolve the table display issue related with #1942. But when I do this PR, I find other 2 issues in livy interpreter.
* livy integration is never run due to refactoring of travis script in #1786.
* pyspark integration would fail
### What type of PR is it?
[Bug Fix | Improvement]
### Todos
* [ ] - Task
### What is the Jira issue?
https://issues.apache.org/jira/browse/ZEPPELIN-2015
### Screenshots (if appropriate)
### Questions:
