is preferred for multi inner join queries (maryannxue: rev

> Original Estimate: 24h

> We enable an option called "FAVOR_STAR_JOIN" to allow for choosing different
> execution plans for multi inner join queries.
> For example:
> select * from A inner join B on A.ab_id = B.ab_id inner join C on A.ac_id =
> C.ac_id and B.bc_id = C.bc_id;
> When using star-join optimization, the execution steps will be like:
> hash B, hash C --> join A
> If star-join is turned off, the execution steps will be like:
> hash A --> join B --> hash temp result AB --> join C
