Resolve syft.lib.python.Any in the code base

[madhavajay]

Description

Go through and find all uses of syft.lib.python.Any and either fix them if the functionality already exists, or add a TODO and Issue to github to describe them.

Some of these can be solved with things like a Numeric UnionGenerator.

Definition of Done

All our syft.lib.python.Any remaining in the code base have been checked and fixed or noted down as TODO.

Hey @madhavajay, so this issue requires to change all syft.lib.python.Any in __init__.py in src/syft/lib/python, right?

So for example this method ("syft.lib.python.List.pop", "syft.lib.python.Any") needs changing of Any with let's say UnionGenerator, right?

So, considering this case what should go inside UnionGenerator, can you help me with that, I am a bit confused.

This might need to be part of the broader live pointers work.
