pylint 2.8 introduces consider-using-with error, suggesting
to use the 'with' block statement when possible.
Modify all subprocess.Popen call to use the 'with' statement,
except the one in __init__ of QemuIoInteractive class, since
it is assigned to a class field and used in other methods.

[mreitz: Disable bad-option-value warning in the iotests' pylintrc, so
that disabling consider-using-with in QemuIoInteractive will
not produce a warning in pre-2.8 pylint versions]

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").
