Provide a Dockerfile for SWProxy

[sebastianneubert]

Hi,

I'm relativly new to Python and the requirements installing on a Mac are not so funny.

Idea: Provide a Dockerfile for Python, where are all requirements are installed and the proxy is fully running with a host:port combination. So it's only a docker build and a docker run and the proxy will run.

I tried it by myself and the output is like:
