[ZEPPELIN-1515] Use Hadoop-FileSystem api to implement NotebookRepo ### What is this PR for? With this PR, I attempt to use Hadoop-filesystem API to implement `NotebookRepo`, which in my opinion is very generic in nature, as with this we will be able to support multiple scheme of the URI like local file system `file:///`, Hadoop file system `hdfs://localhost:8020`, S3 etc. So far I have tested this only with local and HDFS. ### What type of PR is it? [Improvement] ### Todos * [ ] - Periodic refresh of kerberos ticket. ### What is the Jira issue? * https://issues.apache.org/jira/browse/ZEPPELIN-1515 ### How should this be tested? In zeppelin-site.xml enable these two configs; to write into HDFS. ``` <property> <name>zeppelin.notebook.storage</name> <value>org.apache.zeppelin.notebook.repo.HDFSNotebookRepo</value> <description>notebook persistence layer implementation</description> </property> <property> <name>zeppelin.hadoop.uri</name> <value>hdfs://localhost:8020</value> <description>The scheme of the URI determines a configuration property name, fs.scheme.class whose value names the FileSystem class. e.g. `hdfs://localhost:8020`, or `file:///` </description> </property> ``` ### Screenshots (if appropriate) ### Questions: * Does the licenses files need an update? N/A * Is there breaking changes for older versions? N/A * Does this needs documentation?
