### How should this be tested?

1. Run a notebook or paragraph which takes some times. Paragraph which could show progress (%) would be more appreciated. Confirm that its status is 'RUNNING'.
2. Call ```http://<zeppelin host>:<zeppelin port>/api/notebook/job/<notebook id>``` to see if it has 'progress' field in JSON.

### Questions:

* Is there breaking changes for older versions? (No)
* Does this needs documentation? (Yes or no. Output of the JSON format could be updated, but it could be treated as not mandatory.)
