Fix: Enable LLM-as-Judge base model evaluation integration tests, Add cleanup mechanism for MC dataset integ test (#5576)

* Add cleanup mechanism for MC dataset integ test

* Fix integ test for test_llm_as_judge_base_model_fix

* Further fix for the same LLM as judge integ test failure

* Rollback fix in src code

* Update error ahndling for sagemaker-train show results util
