Python 3.11 dropped compat inspect.getargspec. As the roles and modules need to support Python2 and Python3, the code for getargspec has been copied from Python 3.10 and is added as a fallback as soon as getargspec can not be imported from inspect. The copied getargspec is using getfullargspec internally. Fixes: #855 (Python's inspect.getargspec was removed in version 3.11)
