* This removes the need to repeat default config values in a YAML for the sole purpose allowing users to override the values with the `--override` flag.
* Remove unnecessary `assert` in `src/aiq/data_models/common.py` as this is actually already handled by the code, allowing users to prototype config classes directly in the interpreter.
* Add unittests for the `LayeredConfig` class.
