    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.
