Pylint complains about _ignore_ in enum classes

[Hawk777]

Bug description

A field called _ignore_ in an enum class should not cause an invalid-name complaint. It is a special field whose name is dictated by the standard library and cannot be changed.

Consider the following code:

import enum


class MyEnum(enum.Enum):
    FOO = enum.auto()
    BAR = enum.auto()
    _ignore_ = ["BAZ"]
    BAZ = 42

Configuration

No configuration file needed.

Command used

pylint test.py

Pylint output

Will need an astroid update to be effective.
