Yeah. The counts can help us understand the pruning rate of the search 
space. When CBO join reordering is very slow, we can check the counts.

Where should we check the count? Whom do we want to expose it to?
How about a debug level log?

Does it make sense to introduce some counts to decide how many new JoinPlan 
we build?

We can find out what we pruned in the search. It can easy for us to ensure 
no regression happened when we improve the codes in the future.
