Jungtaek Lim 3bfd97e236 ZEPPELIN-511 REST API: Insert / Retrieve / Move / Delete operation for paragraph
### What is this PR for?

This issue is intended to fill gap between REST API and WebSocket operations.
For now we can only access notebook and paragraph to READONLY (not writing) via REST API but after this PR, we can insert / retrieve / move / delete paragraph via REST API.

### What type of PR is it?

Feature

### Todos

### Is there a relevant Jira issue?

https://issues.apache.org/jira/browse/ZEPPELIN-511

### How should this be tested?

Please follow the explanation of added REST APIs from rest-notebook.md.

### Screenshots (if appropriate)

### Questions:
* Does the licenses files need update? (No)
* Is there breaking changes for older versions? (No)
* Does this needs documentation? (Yes, I've addressed it.)

Zeppelin REST API

Zeppelin provides several REST APIs for interaction and remote activation of zeppelin functionality.

All REST APIs are available starting with the following endpoint http://[zeppelin-server]:[zeppelin-port]/api

Note that zeppelin REST APIs receive or return JSON objects, it is recommended for you to install some JSON viewer such as JSONView

If you work with zeppelin and find a need for an additional REST API please file an issue or send us mail
