1c23f21388 [ZEPPELIN-2707][DOCS][HOTFIX] fix: broken image URLs in 0.8.0-SNAPSHOT doc
### What is this PR for?

fix: broken image URLs in 0.8.0-SNAPSHOT doc

using the path `/asset` (the absolute path) for image URLs is actually invalid. That's because each version has its own image directory. So they should use the relative path. `{{BASE_PATH}}`

```
➜  asf-zeppelin tree site | grep asset
├── assets # root asset, we shouldn't use it in versioned doc.
│   │   ├── assets
│   │   ├── assets
│   │   ├── assets

c87fa53a3a [ZEPPELIN-2298] Remove -Ppyspark build profile
### What is this PR for?
Currently users who build Zeppelin from source need to include `-Ppyspark` to use `%pyspark` with embedded local Spark. But it's quite inconvenient to write this build profile every time we build i think. So I removed `-Ppyspark` and make pyspark related libraries automatically downloaded when we build Zeppelin.

### What type of PR is it?
Improvement

### Todos
* [x] - remove the rest of `-Ppyspark` build profile in `dev/create_release.sh`, `dev/publish_release.sh`, and `docs/install/build.md` after getting feedback

### What is the Jira issue?
[ZEPPELIN-2298](https://issues.apache.org/jira/browse/ZEPPELIN-2298)

### How should this be tested?
1. Apply this patch
2. Build source with below command
```
mvn clean package -DskipTests -pl 'zeppelin-interpreter, zeppelin-zengine, zeppelin-server, zeppelin-display, spark, spark-dependencies'

```
Aftr this step, there will be `pyspark` dir under `ZEPPELIN_HOME/interpreter/spark`. Before this PR, only `dep` dir and `zeppelin-spark_2.10-0.8.0-SNAPSHOT.jar` is generated without `-Ppyspark` build profile.

4. Restart Zeppelin. To make sure, run any python code e.g.
```
%pyspark
print("Hello "+z.input("name"))
```
It should be run successfully without any error

### Screenshots (if appropriate)
 tl;dr Without `-Ppyspark` profile
 - Before

### Questions:
* Does the licenses files need update? no
* Is there breaking changes for older versions? no
* Does this needs documentation? no

I want to include `SparkR` by default(= remove `-PsparkR` build profile) like this as a next step. I want to ask how Zeppelin community think about this.

85d4df4f0c [ZEPPELIN-1219] Add searching feature to Zeppelin docs site
### 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.
![screen shot 2016-08-03 at 4 49 59 am](https://cloud.githubusercontent.com/assets/10060731/17342828/f2908be8-5935-11e6-8eee-b189677c0531.png)
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?
Improvement & Feature

### Todos
* [x] - Keep consistency for all docs pages' `Title`
* [x] - Add some overview sentences to all docs pages' `Description` section (this will be used as the result preview)
* [x] - Add apache license header to all docs page (some pages are missing the license header currently)
* [x] - Add LICENSE for `lunr.min.js`

### What is the Jira issue?
[ZEPPELIN-1219](https://issues.apache.org/jira/browse/ZEPPELIN-1219)

### How should this be tested?
1. Apply this patch and build `ZEPPELIN_HOME/docs` dir -> please see [docs/README.md#build-documentation](https://github.com/apache/zeppelin/tree/master/docs#build-documentation)
2. Click `search` icon in navbar and go to `search.html` page
3. Type anything you want to search in the search bar (i.e. type `python`, `spark`, `dynamic` ... )

5975125f18 [ZEPPELIN-1018] Apply auto "Table of Contents" generator to Zeppelin docs website
### 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)
2.  Visit some docs page. Then you can see TOC in the header of page.

### Screenshots (if appropriate)
 - Automatically generated TOC in Spark interpreter docs page

### 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
