[nicolargo]

Use data class as default data:

• for stats history
• for all "real time stats"

Ex:

>>> from pydantic import BaseModel
>>> class Toto(BaseModel):
...     value: int
...     key: str
>>> i = Toto(key="cpu", value=10)
>>> i
Toto(value=10, key='cpu')
>>> i.model_dump_json()
'{"value":10,"key":"cpu"}'
>>> i.model_dump()
{'value': 10, 'key': 'cpu'}

>>> d =  i.model_dump()
>>> import sys
>>> sys.getsizeof(i)
72
>>> sys.getsizeof(d)
184

First step is to create a DataClass catalog with all the class used by Glances Stats.
