Refactor Core API: Make Sure the Argument Names are In Sync with Scenario Attributes and GUI Fields

[popescu-v]

Description

Currently, there are some mismatches between the Core API function parameters and the corresponding features in the GUI and / or the Khiops scenarios. For instance, use_complement_as_test: bool=[True | False] from the Core API is mapped to test_database_mode: str=["Complementary" | None].

Questions/Ideas

• Inventory all cases of such parameter remappings (a.k.a. "preprocessing", in _preprocessing helper functions)
• Reduce these preprocessings as much as possible, the goal is to have a mapping between Core API parameters and scenario comands which is as straightforward as possible.
• Caveat emptor: We however need to observe Python naming conventions as much as possible.

Audit the needed changes for 11.0.1.0.
