[ZEPPELIN-3098] Livy Interpreter fails if row contains newline or tab
### What is this PR for?
This PR fixes the issue of newlines and tabs breaking results in the SQL
interpreter in Livy.
The Livy interpreter will return incorrect results if a row contains \n or
\t characters.
In the case of the newline, the result will be:
Line is missing from results if the \n appears anywhere but the end of a
cell
`String index out of range: 17` if it appears at the end of a cell
In the case of the tab, the result will be misaligned columns if the tab
appears in the middle of a cell
The output showing these error is attached.
I have changed the parsing and any newline or tab characters will be escaped
