> Deprecate the use of redundant column in colunm stats related tables

> Project: Hive

> The stats tables such as TAB_COL_STATS, PART_COL_STATS have redundant columns
> such as DB_NAME, TABLE_NAME, PARTITION_NAME since these tables already have
> foreign key like TBL_ID, or PART_ID referencing to TBLS or PARTITIONS.
> These redundant columns violate database normalization rules and cause a lot
> of inconvenience (sometimes difficult) in column stats related feature
> implementation. For example, when renaming a table, we have to update
> TABLE_NAME column in these tables as well which is unnecessary.
> This JIRA is first to deprecate the use of these columns at HMS code level. A
> followed JIRA is to be opened to focus on DB schema change and upgrade.
