Version compatible inspect handling for class parameters

[johnlarkin1]

getargspec was deprecated in Python 3.0, but finally removed in Python 3.11. For reference: Pylons/pyramid#3688

That seems like a valid amount of time for us to have fixed it.

We can do our best effort and if the user is running a Python version that still has getargspec use that, but if they have getfullargspec which is available in Python 3.11, we can use that.
