> Fix For: v2.3.0

>
> If the design for an existing cube is not good, which means its prebuilt
> cuboid set is not suitable for query, there should be a way to adjust this
> cuboid set. This is phase two of cube planner, also called cube optimization.
> Its data source should be base cuboid rather than the original data source,
> like hive, for the original one may be changed. Thus for cubing jobs, like
> cube optimization, we introduce a new input , base cuboid formatted by
> sequence file.
