JoinPlan

Partial join order in a specific level.

itemIds: Set of item ids participating in this partial plan.
plan: The plan tree with the lowest cost for these items found so far.
joinConds: Join conditions included in the plan.
planCost: The cost of this plan tree is the sum of costs of all intermediate joins.
