Cloning a notebook does not copy `noteParams`, `noteForms` and `config`

Cloning a notebook only copies the `name` and `paragraphs` attributes of a `Note` object. It should also copy other attributes like `noteParams`, `noteForms` and `config`.

Function `Note cloneNote` inside `org.apache.zeppelin.notebook.Notebook` is where the functionality lies

***

Note newNote = createNote(subject);

***

newNote.setName(newNoteName);

***
newNote.setCronSupported(getConf());

List<Paragraph> paragraphs = sourceNote.getParagraphs();
for (Paragraph p : paragraphs) { newNote.addCloneParagraph(p, subject); }

***
noteSearchService.addIndexDoc(newNote);
newNote.persist(subject);
return newNote;

Is this an intended behavior, and if so what is the reason for it? If not, I'd like to raise a PR for the same.
