[PATCH 2/3] iotests: Disable unsubscriptable-object in pylint

[Kevin Wolf]

When run with Python 3.9, pylint incorrectly warns about things like
Optional[foo] because it doesn't recognise Optional as unsubscriptable.
This is a known pylint bug:

    https://github.com/PyCQA/pylint/issues/3882

Just disable this check to get rid of the warnings.

Disabling this shouldn't make us miss any real bug because mypy also
has a similar check ("... is not indexable").
