AhyoungRyu 5ddc1ef87e [ZEPPELIN-996] Improve first page and dropdown menu in documentation site ... ### What is this PR for? Current Zeppelin documentation site is little bit hard to find a way for Zeppelin beginners. It will not easy to improve this at a time, but I did the below as a start of this work. 1. Restructured dropdown menu and added each category names 2. Added a overview list(with short description) to first page of website (index.md) so that people can look through the overall contents in Zeppelin website at a glance.
