layday 78934db631 PropagateClassVars to sub-models (#2179) ...

* Propagate`ClassVar`s to sub-models

Currently, if a `ClassVar` is defined on a model and re-defined
on a sub-model omitting the `ClassVar` annotation, Pydantic produces an
unrelated error:

    NameError: Field name "..." shadows a BaseModel attribute ...

This check was introduced to prevent shadowing Pydantic's own methods
and attributes defined on the `BaseModel` class.  Following this change,
class variables (that is, variables annotated with `ClassVar`)
defined on parent models will be inherited by sub-models and
will be overwritable without having to reapply the annotation.

Closes #2061.

* docs: explain how attributes are excluded and when to use `PrivateAttr`
