It only runs notebooks that have differences from the Git base_branch.

Args:
test_paths_file (str):
Required. The new-line delimited file to folders and files that need checking.
Folders are checked recursively.
base_branch (str):
Optional. If provided, only the files that have changed from the base_branch will be checked.
If not provided, all files will be checked.
output_folder (str):
Required. The folder to write executed notebooks to.
variable_project_id (str):
Required. The value for PROJECT_ID to inject into notebooks.
variable_region (str):
Required. The value for REGION to inject into notebooks.
should_parallelize (bool):
Required. Should run notebooks in parallel using a thread pool as opposed to in sequence.
should_use_separate_kernels (bool):
Note: Dependencies don't install correctly when this is set to True
See https://github.com/nteract/papermill/issues/625
Required. Should run each notebook in a separate and independent virtual environment.
