class_docstr: Change the relative flag of the given relative optimization configuration
  to False. This is needed in order for the new opt config to pass ModelBridge
  that requires non-relativized opt config.
  
  Also transforms absolute data and opt configs to relative.
  
  Requires a modelbridge with a status quo set to work.
  
  Abstract property control_as_constant is set to True/False in its subclasses
  Relativize and RelativizeWithConstantControl respectively to account for
  appropriate transform/untransform differently.
