AhyoungRyu 70d22d3d0a [ZEPPELIN-998] Extend install.md -> Quick Start
### What is this PR for?
Most of other projects have **Quick Start** or **Getting Started** page for the beginner. Currently, Zeppelin also has [Zeppelin Install](https://zeppelin.apache.org/docs/0.6.0-SNAPSHOT/install/install.html) which is similar with those kind of instruction page. But it has only contents that explain just installation and configuration. So I updated this page to **Quick Start** so that it can include step by step guide for the beginners.

### What type of PR is it?
