[FEATURE] Windows environment configuration

[dietWall]

TODO:
provide an environment setup script for windows:

on first test on windows:

• venv creation was missing and had to be created manually
• python had to be installed manually
• run Set-ExecutionPolicy -ExecutionPolicy RemoteSigned somehow (user/system etc.)
  -- this has to be done manually and is required to activate venv

besides of this ssh-keys.py has done its work. But has overwritten old keys.

So therefore: TODO:

• provide a powershell script that installs latest python and adds it to path
• creates a venv and installs requirements
• provide a test for Windows environment (setups the environment - deploys some keys to WSL)
