feat(pipenv): support dynamic python selection

[viceice]

ref: renovatebot/docker-python#24, renovatebot/docker-pipenv#25

closes: #6035

[viceice]

we can check pipfile.lock (json) for used python version too:

Should come from the Pipfile itself though? I would guess that if the Pipfile specifies it then it's in the lock, but otherwise not.

[viceice]

I haven't found any Pipfile(.lock) with a pipenv version defined.

Waiting on renovatebot/docker-python#30

[rarkins]

I'll fix this up

Won't this install pipenv even for users who are running with binarySource=auto?

[rarkins]

@viceice perhaps we need to give user 1000 permissions on Permission denied: '/usr/local/pyenv/versions/3.7.7/lib/python3.7/site-packages/ ?

[viceice]

Will look at it

[viceice]

@rarkins why not always install pipenv on run? So we don't need it in full image. I think pip will do nothing, if it's already installed.

If people are running this in non-Docker I don't think we should be installing software.
