> Add fat API to create cube & delete cube

> Key: KYLIN-4579
> URL: https://issues.apache.org/jira/browse/KYLIN-4579
> Project: Kylin
> Issue Type: Improvement
> Components: REST Service
> Reporter: Zhong Yanghong
> Priority: Major
>
> If there're many backend kylin instances, kylin instances will broadcast
> metadata change asynchronously. In this case, when user try to create a cube
> by program, whose normal process is to
> # load tables
> # create model
> # create cube
> Since this process is not atomic and the related three requests will be sent
> to backend instances randomly, it probably causes exceptions due to the
> metadata update delay.
> For example, if there're two kylin instances, K1 & K2. User sends "load
> tables" request to K1, then sends "create model" request to K2. If K2 is not
> notified with metadata update in time, it will fail to initialize the model
> and throw exceptions.
> To deal with this issue, it's better to create a fat API to create cube &
> delete cube, which will make it possible to send all the step request to one
> server.
