Proposal for new Job Engine

[周千昊]

Currently Kylin has its own Job Engine to schedule cubing process. However
there are some demerits
1. It is too tightly couple with cubing process, thus cannot support other
kind of jobs easily
2. It is hard to expand or to integrate with other techniques (for example
Spark)
Thus I have proposed a refactor for the current job engine.
