[ZEPPELIN-1729] With CRLF line endings, Livy gets HTTP 500 errors
### What is this PR for?
When you paste text on Windows, you may inadvertedly add some Carriage
Return control characters along with it. When this happens in a Livy paragraph
in Zeppelin 0.6.0, execution of that paragraph will fail with a "500 Internal
Server Error" message. This is because `LivyHelper` does not properly sanitise
its input when generating a JSON payload for the Livy server. This PR takes the
subset for the resolution of
[ZEPPELIN-1430](https://issues.apache.org/jira/browse/ZEPPELIN-1430/) that
should resolve this issue.
### What type of PR is it?
Bug Fix
### What is the Jira issue?
<https://issues.apache.org/jira/browse/ZEPPELIN-1729/>
### How should this be tested?
Paste the following code in a new paragraph, ensuring that lines are ended
by CRLF rather than LF:
%livy.pyspark
import datetime
import json
This can be easily realised on Windows, by copy-pasting this code from
Notepad. Then, try to execute the paragraph. Without the fix, a "500 Internal
Server Error" message should appear. With the fix, the paragraph will
successfully execute (and do nothing interesting).
### Questions:
* Does the licenses files need update? No.
* Is there breaking changes for older versions? No.
* Does this needs documentation? No.
