[ZEPPELIN-1514] Make atom, rss, sitemap file not to be searched

### What is this PR for?
I excluded some docs pages from [search 
page](https://zeppelin.apache.org/docs/0.7.0-SNAPSHOT/search.html) in Zeppelin 
documentation site. This can be done by removing `title` value in [front 
matter](https://jekyllrb.com/docs/frontmatter/) as I did same for 
`pleasecontribute.md` in 
[here](https://github.com/apache/zeppelin/pull/1266/commits/6e775f5c28b80538fff1484b4eb1f66c795ca2c1).

### What type of PR is it?
Bug Fix

### What is the Jira issue?
[ZEPPELIN-1514](https://issues.apache.org/jira/browse/ZEPPELIN-1514)

### How should this be tested?
1) build gh-pages (website) branch
```
JEKYLL_ENV=production bundle exec jekyll build
mkdir -p tmp/zeppelin_website/docs/
cp -r  _site/ /tmp/zeppelin_website/
```

2) build this patch(docs) and copy it under docs/0.7.0-SNAPSHOT of website
```
cd ZEPPELIN_HOME/docs/
bundle exec jekyll build --safe
cp -r  _site/ /tmp/zeppelin_website/docs/0.7.0-SNAPSHOT/
```

3) start httpServer
```
cd /tmp/zeppelin_website
python -m SimpleHTTPServer
```

4) browse `http://localhost:8000`

### Screenshots (if appropriate)
The below pages shouldn't be searched
