Introduce functionality for chunking experiments

[mcw92]

This PR introduces functionality for chunking experiments. The following changes have been made:

• Make the synthetic data generation consistent throughout the code. This means that in the serial case, the dataset generated with generate_and_distribute_synthetic_dataset without local or global imbalances equals the completely balanced dataset generated with make_classification_dataset when using the same random state. This ensures comparability of the strong scaling experiment series with and without chunking as the same datasets are created when passing the same random state.
• Fix passing additional keyword arguments in both train_parallel_on_synthetic data and train_parallel_on_balanced_synthetic_data. This was completely missing in the former case. In addition, the argument parser was lacking some of the keyword arguments used in sklearn's make_classification and train_test_split used under the hood.
