* Teach mypy plugin that validator methods are classmethods
For your consideration: a patch which implements the suggestion I made here:
https://github.com/samuelcolvin/pydantic/discussions/4101
Briefly: pydantic automatically wraps validator methods using
`@classmethod`. Hence the first argument to a user-provided validator
should be `cls`. But mypy doesn't know this: it analyses validator
methods like any other regular method, believing the first parameter
`cls` to be a model instance (usually denoted self).
This means that if one annotates `cls` as `Type[...]` then mypy
believes raises an error:
error: The erased type of self "Type[temp.Model]" is not a supertype of its class "temp.Model"
I concede that this is an extremely niche thing. The only tangible
end-user benefit I can think of is that it'll stop you from calling
instance methods in a validator.
----
I haven't written a mypy plugin before, so this is a bit of a
hack-until-it-works. But it was more straightforward than I expected to
get something working!

* feature: add a `frozen` parameter to config
For now, `frozen` is a strict duplication of `allow_mutation` parameter
i.e. setting `frozen=True` does everything that `allow_mutation=False` does.
NB: this does not change the behavior of `allow_mutation`.
In next commit, setting `frozen=True` will also make the BaseModel hashable
while the existing behavior of `allow_mutation` will not be updated.
* refactor: factorise immutability tests
* feature: generate a hash function when frozen is True
Now, setting `frozen=True` also generate a hash function for the model
i.e. `__hash__` is not `None`. This makes instances of the model potentially
hashable if all the attributes are hashable. (default: `False`)
* reviewer feedback: use hash of the class instead of the super
* reviewer feedback: fix spelling checks
* reviewer feedback: update changes description
* test: remwork mypy tests in order to catch only frozen related errors
Before: there were errors about other stuff than frozen behavior
After: The modification catch only errot related to the frozen behavior
* test: split test_immutablity in 2 functions
One function tests the behavior: 'the model is mutable'
The other tests the behavior:OC 'the model is immutable'
* test mutability: remove the unnecessary parametrization
* test immutability: remove assertion that do not test frozen behavior
