Python PIP install should do it locally

[Asad Memon]

To avoid permission issues and version mismatches between projects, pip should install using --user and maybe inside .zero/pip_modules folder. This would also likely require appending PATH to these modules as environment variable when spawning python process in handler-python.

I'd say python_modules instead of pip_modules so we stick to the node convention.

[Asad Memon]

You are right. python_modules it is.
