[ZEPPELIN-4504]. Fix searching of keywords in notebooks
### What is this PR for?
This PR improve the lucene search via storing the index in filesystem by
default. So that even after zeppelin restart, we can still recover the index.
This PR introduce several new configurations:
* zeppelin.search.index.path. --> folder path for storing lucene index
* zeppelin.search.use.disk --> whether use disk as index storage.
* zeppelin.search.index.rebuild --> whether rebuild index when
zeppelin start
### What type of PR is it?
[Bug Fix]
### Todos
* [ ] - Task
### What is the Jira issue?
* https://issues.apache.org/jira/browse/ZEPPELIN-4504
### How should this be tested?
* CI pass
### Screenshots (if appropriate)
### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
Author: Jeff Zhang <zjf...@apache.org>
Closes #3681 from zjffdu/ZEPPELIN-4504 and squashes the following commits:
