ClassVar fields are ignored / not recognized

[skewty]

Describe the bug
When creating a model that has a field type hinted with "typing.ClassVar", it is ignored / not recognized.

To Reproduce

from typing import ClassVar
from pydantic import BaseModel

class FooModel(BaseModel):
    special_name_a: ClassVar[str] = 'CEO'
    _special_name_b = 'CFO'
    __special_name_c__ = 'Janitor'

    name: str

FooModel.|   # cursor at the pipe
# PyCharm does not show existence of `special_name_a` field.
# PyCharm does not show existence of `_special_name_b` field.
# PyCharm does show existence of `__special_name_c__` field.
# Pydantic recognizes the type hint and does not make a model field named 'special_name_a'.
# Pydantic recognizes the leading underscore and does not make a model field named '_special_name_b'.
# Pydantic recognizes the leading and trailing underscores and does not make a model field named '__special_name_c__'.

Expected behavior
I expect PyCharm (the plug-in) to recognize the class level fields. Both 'special_name_a' and 'special_name_c' should be presented in auto-complete. I don't expect the "protected" field of _special_name_b to show up but PyCharm should be made aware of it so people who want to show protected fields will also see it.

You already recognize the magics (__magic__) as class level. You should be able to make use of that code.

Environments (please complete the following information):

• IDE: PyCharm Pro 2020.2.1
• OS: PopOS 20.04
• Pydantic Version 1.4
• Plugin version 0.1.11

Wow, that was super fast and I was so excited I closed down everything to try it out and like you said it works!
Thanks, so much. It will make a rather large difference in the code base I am working in.
I am excited to share the good news with my co-workers as well.

Thank you so much for the time you have put into this fix and the plug-in.
