PYPE-649: projects don't guarantee backwards compatible environment

[mkolar]

Problem

as the title is partly explaining we are not able to secure backward compatibility for old projects as almost all releases of pype-config are breaking some compatibility.. So if we open project after a year we are not able to run it as the project overwrite will miss some of the needed features used at the time.

Suggestion:

we could store json file inside of a project config override which would preserve all versions and tags and requirements with python version synergy at the time of project creation.

in next step we would develop mechanism which would generate pype_venv into each project overwrite folder with all required packages for project_overwrite_root/.venv//<python_version>

should be resolved by #221
