Provide a System Testing Framwork for Kylin Cluster

https://cwiki.apache.org/confluence/display/KYLIN/KIP-2+System+testing+framework+for+Kylin

I wonder if we could implement a CI/CD framework for apache kylin to improve test coverage of Kylin important features. We need at least:

• Automatic build/package env to make package easier.
• Automatic deployment env for Hadoop & Kylin deployment.
• Testing framework based on Rest API/CLI/JDBC.
