support Poetry vens

[turbotimon]

Request to support virtual environments created by Poetry normally located at /home/<username>/.cache/pypoetry/virtualenvs/. Or, the possibility to add own configurations (paths to venv folder)

It looks like the tool does it not right now:

$ poetry env info

I see one of three Poetry venvs, the first I defined. Further Poetry venvs don't add to the list
