Review comment:
Same as above. `get_table_core` with retrieve column stats is a public
method but not part of the Metastore API, hence I think I can do same as above.
Thoughts?

> The goal is to avoid computation of column stats by engines to step on each
> other, e.g., Hive and Impala. In longer term, we may introduce a common
> representation for the column statistics stored by different engines.
> For this issue, we will add a new column 'engine' to TAB_COL_STATS HMS table
> (unpartitioned tables) and to PART_COL_STATS HMS table (partitioned tables).
> This will prevent conflicts at the column level stats.
