Couldn't get the paragraph result ("zeppelin.paragraph.result.table") from Resource Pool.

Hi,

In 0.8.2, I can use the following code to retrieve the paragraph results.

%python
ic = z.getInterpreterContext()
rp = ic.getResourcePool()
rp.get(notebookID, paragraphID, "zeppelin.paragraph.result.table")

It's very easy for me to transfer the data among the notebooks/paragraphs. 

But in 0.9.0, the call always returns nothing.

Has this function been removed?

Thanks.
