AST-1467: use get_start_times instead of glob to get intermediate pipeline products
With this MR the filenames generated when skipping predict_1 and predict_3 are generated using the get_start_times function instead of glob. The data_fraction and mintime parameters are also added to the workflow (it was needed to make the test_logging work with more than 1 time chunk)
