[5pt]Enhance environment markers with python_version taken from package metadata

[fridex]

Is your feature request related to a problem? Please describe.

Pipenv added a new feature where each dependency has the environment marker python_version taken from package metadata. It might be a good idea to include such an environment marker in Thoth's adviser as well. It will not affect the resolution process anyhow, but will create more explicit Pipfile.lock with relevant python_version environment markers.

Describe the solution you'd like

• [ ] sync information about python_version into the database from solver runs
• [ ] propagate python_version information in a form of an environment marker in the resulting lock file

Describe alternatives you've considered

Keep the solution as-is.

This would be a nice feature, but not "must-have". This behavior is partially documented. If users use overlays properly and have their environments setup correctly, this feature has no effect.
