### What is this PR for?
Currently, the parameter "project" is defined with "kylin.query.project" in properties. It's not convenience when query Kylin among different projects. May I propose introducing %kylin(project_name) at the interpreter runtime? If not set, the default project will work, otherwise, will use explicit project_name for the query request.

Apache Kylin Interpreter for Apache Zeppelin
Overview
Apache Kylin is an open source Distributed Analytics Engine designed to provide SQL interface and multi-dimensional analysis (OLAP) on Hadoop supporting extremely large datasets, original contributed from eBay Inc. The interpreter assumes that Apache Kylin has been installed and you can connect to Apache Kylin from the machine Apache Zeppelin is installed.
To get start with Apache Kylin, please see Apache Kylin Quickstart.
