[ZEPPELIN-699] Return Paragraph execution result for the REST API
### What is this PR for?
Right now, when calling the REST API
`http://<ip>:<port>/api/notebook/job/<note_id>/<paragraph_id>` Zeppelin always
returns **OK** as shown by this source code:
https://github.com/apache/incubator-zeppelin/blob/master/zeppelin-server/src/main/java/org/apache/zeppelin/rest/NotebookRestApi.java#L477
This ticket will update the behavior so that Zeppelin also return the
result of the paragraph execution

* Create a new note
* In the first paragraph, put the following code
```scala
z.getInterpreterContext().getParagraphId()
println("Current time = "+new java.util.Date().toString)
