> Remove the EvaluationContext parameter from TransformEvaluatorFactory.forApplication() and move it to TransformEvaluatorRegistry.defaultRegistry(), and pass it to all of the TransformEvaluatorFactories created in that constructor.
> A single EvaluationContext is produced per pipeline run. TransformEvaluatorFactories are also produced once per pipeline run, as they are stateful (especially with regards to sources). This change will both ensure that Evaluators cannot be reused across pipelines, and cleans up the signature of the TransformEvaluatorFactory interface.
