Make --verbose option additive

[glensc]

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

pip install --verbose option is additive, since pipenv flag is not, there's no way to pass --verbose --verbose to pip.

$ pip install --help
...
  -v, --verbose               Give more output. Option is additive, and can be used up to 3 times.

Describe the solution you'd like

Make pipenv install --verbose option is additive and pass it to pip

Additional context

I'm trying to run pipenv install for package that take long to compile from sources, would like to see some output of the progress.
