I didn't create a JIRA issue, it doesn't look like that is nessicary for website updates? If it is, I'm sorry I'll go make one. Sorry, I'm new.

### What is this PR for?
As more and more document pages are added, it's really hard to find specific pages. So I added searching feature to Zeppelin documentation site([jekyll](https://jekyllrb.com/) based site) using [lunr.js](http://lunrjs.com/).
- **How does it work?**
I created [`search_data.json`](6e02423f54/docs/search_data.json) which is used for docs info template. `lunr.js` combines all of the text from all of the docs in `docs/` into `_site/search_data.json`. It looks like below.

All the info are comes from [Jekyll YAML front matter](https://jekyllrb.com/docs/frontmatter/) variables. (i.e. title, group, description.. that's why I rewrote all docs' title and description.)
[search.js](6e02423f54/docs/assets/themes/zeppelin/js/search.js) will do this job using this data!
### What type of PR is it?

### What is this PR for?
I added auto TOC(Table of Contents) generator for Zeppelin documentation website. TOC can help people looking through whole contents at a glance and finding what they want quickly.
I just added `<div id="toc"></div>` to the each documentation header. [`toc`](https://github.com/apache/zeppelin/compare/master...AhyoungRyu:ZEPPELIN-1018?expand=1#diff-85af09fb498a5667ea455391533f945dR3) recognize `<h2>` & `<h3>` as a title in the docs and it automatically generate TOC. So I set a rule for this work. (I'll write this rule on `docs/CONTRIBUTING.md` or [docs/howtocontributewebsite](https://zeppelin.apache.org/docs/0.6.0-SNAPSHOT/development/howtocontributewebsite.html)).
```
# Level-1 Heading <- Use only for the main title of the page
## Level-2 Heading <- Start with this one
### Level-3 heading <- Only use this one for child of Level-2
toc only recognize Level-2 & Level-3
```
Please see the below attached screenshot image.
### What type of PR is it?
Improvement & Documentation
### Todos
* [x] - Add TOC generator
* [x] - Apply TOC(`<div id="toc"></div>`) to every documentation and reorganize each headers(apply the above rule)
* [x] - Fix some broken code block in several docs
* [x] - Apply TOC to `r.md` (Currently R docs has some duplicated info since [this one](d5e87fb8ba) and [this one](7d6cc7e991) )
* [x] - Apply TOC to `install.md` after #1010 merged
* [x] - Apply TOC to `interpreterinstallation.md` after #1042 merged
### What is the Jira issue?
[ZEPPELIN-1018](https://issues.apache.org/jira/browse/ZEPPELIN-1018)
### How should this be tested?
1. Apply this patch and build `docs/` with [this guide](https://github.com/apache/zeppelin/tree/master/docs#build-documentation)

### Questions:
* Does the licenses files need update?
No. Actually I used [jekyll-table-of-contents#copyright](https://github.com/ghiculescu/jekyll-table-of-contents#copyright). But I don't need to add a license for this :)
* Is there breaking changes for older versions? No
* Does this needs documentation? Maybe
