Provide own getargspec for roles and modules with Python 3.11

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)
