> People often want different variants of planner rules. An example is 
> {{FilterJoinRule}}, which has a 'boolean smart’ parameter, a predicate (which 
> returns whether to pull up filter conditions), operands (which determine the 
> precise sub-classes of {{RelNode}} that the rule should match) and a 
> {{RelBuilderFactory}} (which controls the type of {{RelNode}} created by this 
> rule).
> Suppose you have an instance of {{FilterJoinRule}} and you want to change 
> {{smart}} from true to false. The {{smart}} parameter is immutable (good!) 
> but you can’t easily create a clone of the rule because you don’t know the 
> values of the other parameters. Your instance might even be (unbeknownst to 
> you) a sub-class with extra parameters and a private constructor.
> So, my proposal is to put all of the config information of a {{RelOptRule}} 
> into a single {{config}} parameter that contains all relevant properties. 
> Each sub-class of {{RelOptRule}} would have one constructor with just a 
> ‘config’ parameter. Each config knows which sub-class of {{RelOptRule}} to 
> create. Therefore it is easy to copy a config, change one or more properties, 
> and create a new rule instance.
> Adding a property to a rule’s config does not require us to add or deprecate 
> any constructors.
> The operands are part of the config, so if you have a rule that matches a 
> {{EnumerableFilter}} on an {{EnumerableJoin}} and you want to make it match 
> an {{EnumerableFilter}} on an {{EnumerableNestedLoopJoin}}, you can easily 
> create one with one changed operand.
> The config is immutable and self-describing, so we can use it to 
> automatically generate a unique description for each rule instance.
