Suggestion: Use pydantic for configs

[MaciejKaszynski]

Would be nice to have the configs structure in the code

Right now we are deserializing the config data dynamically:

itf/score/itf/plugins/qemu/config.py

Lines 21 to 31 in e994cb6

	def _dict_to_obj(data):
	"""
	Recursively convert a dictionary to an object with attributes.
	Lists of dictionaries are converted to lists of objects.
	"""
	if isinstance(data, dict):
	return SimpleNamespace(**{key: _dict_to_obj(value) for key, value in data.items()})
	elif isinstance(data, list):
	return [_dict_to_obj(item) for item in data]
	else:
	return data

I think having the structure described by the code is nice for self documenting code + validation of the config.

Pydantic is a common library for this however it would introduce another dependency.
Alternatively there are ways to do this without dependencies:
