[ASTERIXDB-3195][COMP] Add query properties to enumerate all plans.
- user model changes: yes
- storage format changes: no
- interface changes: no
Details:
Add query properties to enumerate all plans without pruning during
join enumeration. This will help debug issues when good plans may
have been pruned off due to incorrect costing or other reasons.
New properties are:
- "cbofullenumlevel": Num of levels to do full join and plan enumeration.
- "cbocpenum": true/false for cartesian product plan generation.

> It would be very useful for testing and debugging purposes to have an
> internal flag to turn off pruning during join enumeration. This will enable
> us to debug issues when good plans may have been pruned off due to incorrect
> costing or other reasons.
> We need to ensure that we don't degrade the current planning process.
