Notebook: (Web) HDFS as a backend storage (Read & Write Mode)
### What is this PR for ?
This PR replaces the PR-1479 by removing any hadoop dependency using
WEBHDFS as a communication protocol (code borrowed from PR1600)
Zeppelin currently supports many backends for storing notes through Apache
Commons VFS.
Apache Commons VFS supports HDFS in readonly mode.
This PR makes HDFS a first class citizen by allowing users to load notes
from / save notes to HDFS.
