Ignore `--user` in virtual environments

See original GitHub issue

What’s the problem this feature will solve?

Ensure that folks who do pip config set install.user true can continue using virtual environments without “–user isn’t visible, aborting” messages. 😃

Describe the solution you’d like

--user does nothing in a virtualenv that does not have system site-packages access.

Alternative Solutions

Maintain status quo. Or #7002. Or something else entirely!

so maybe the general best-practice advice should be to upgrade to 19.4 (20.0?)

Yep.

I feel this doesn’t as much sense if we have saner defaults that work better in this case. Explicit opt-ins shouldn’t be needed then, which should make things easier to manage. : )

@pradyunsg I think this was more to contrast the behavior updated with PR #7155, that is: if --user is indicated anywhere (CLI, environment, configuration) while we are in a virtual environment which does not have system site packages enabled (the default IIRC) then pip aborts.

That said, the reason that this would happen for users is because they would put user = true in config to avoid accidental global installation, so maybe the general best-practice advice should be to upgrade to 19.4 (20.0?) when it is released and then just execute pip install ... which should do the right thing?
