   ### Is your feature request related to a problem or challenge?
   
   `Optimizer` returns early when a rewrite produces a certain plan for the 
second time.
   Producing same plan again is considered a problem. Returning early is to 
prevent (avoidable) failure for the user, however
   
   - it can masks actual problems (we don't know when optimization finishes 
early)
   - it can lead to suboptimal plan being executed, which may be very expensive 
-- for example containing cross join because predicates weren't pushed into the 
join yet
   
   
   
   ### Describe the solution you'd like
   
   Do not mask problems. Let the code fail fast, so that bugs are clear.
   As interim solution, we can have a flag allowing user to recover by 
restoring current lenient behavior.
   
   This can be modelled after existing `datafusion.optimizer.skip_failed_rules` 
config which serves similar purpose.
