Additionally, few other small changes.
* Updated a test fixture to support the latest eval data schema. Somehow I missed doing that previously.
* Updated the `evaluation_generator.py` to use `run_async`, instead of `run`.
* Also, raise an informed error when dependencies required eval are not installed.
* Also, changed the behavior of AgentEvaluator.evaluate method to run all the evals, instead of failing at the first eval metric failure.
