What changes are proposed in this pull request?

Remove the duplicated definitions of spark_session constructor in the following files:

• tests.spark.autologging.ml.test_pyspark_ml_autologging
• tests.evaluate.test_evaluation
• tests.tensorflow.test_keras_pyfunc_model_works_with_all_input_types

Instead, use the defined spark_session constructor already present in tests.utils.test_file_utils.

I had to use # noqa: F401 to ensure that the import doesn't get removed by the linter.
Do you know any better way to do this?
I imagine we could also work with the conftest.py files to do the imports instead of doing it directly in the test file.
