Python 3.11 support?

@cornelinux
It looks like, that current pi-manage is not compatible with Python 3.11:

inspect.getargspec was deprecated in 3.0. Is this already known?

Edit:
Workaround for me was to use inspect.fullargspec instead, and add 3 dummy variables because getfullargspec will return 7 items instead of 4 :

args, varargs, keywords, defaults, foo, foo1, foo2 = inspect.getfullargspec(func)

Your oberservation is correct.
