Use docker-compose to deploy Hadoop and Kylin

We know that Kylin has kylin-it for intergration test, which cover build, query, tools etc. But some complex features, such as system cube, read write separation deployment, jdbc source can not be covered by intergration test. I wonder if we could automate system level testing to cover these important feature.

So the first step is to enable automatic deployment for Kylin and Hadoop. I propose to use docker-compose to make it happen.
