> A logical plan is composed of multiple query blocks. Each logical node must belong to
one query block. A query block instance  provides lots of information. So, it is essential
information in many rewrite rules and optimizer implementations. 
> However, so far, individual rewrite rule or optimizer implementation have dealt with
query block directly. It may be error-prone and cause duplicated codes. This patch refactors
each visitor method of LogicalPlanVisitor to take a query block as a parameter.  
> I'm expecting that this change will provide more convenience for rewrite rules and optimization
development.
