pipenv ignores PIPENV_INSTALL_TIMEOUT

[agelter]

Issue description

It appears that setting PIPENV_INSTALL_TIMEOUT as an environment variable doesn't change the installation timeout used by pipenv. I have a remote location where the internet connection is quite slow and the default of 15 minutes is not long enough.

Looking at pipenv/pipenv/environments.py I see:
PIPENV_INSTALL_TIMEOUT = 60 * 15

Unlike other variables in this file, PIPENV_INSTALL_TIMEOUT doesn't look at the environment for an override. I would have expected something like:

PIPENV_INSTALL_TIMEOUT = os.environ.get("PIPENV_INSTALL_TIMEOUT", 60 * 15)

Expected result

PIPENV_INSTALL_TIMEOUT=$(( 60 * 20 )) pipenv lock

-or-

PIPENV_INSTALL_TIMEOUT=$(( 60 * 20 )) pipenv install

Shouldn't timeout until 20 minutes have passed.

Actual result

pipenv times out after 15 minutes:

Steps to replicate

PIPENV_INSTALL_TIMEOUT=$(( 60 * 20 )) pipenv lock

or similar with a very slow internet connection such that the installation lasts longer than 15 minutes.

I believe PIPENV_INSTALL_TIMEOUT is for installing Python (via pyenv), not packages. The naming is poor, but it is what it is. Also pipenv lock does not install anything.

[agelter]

@uranusjr yes, pipenv lock doesn't install anything, but it does download and parse setup.py files and that's what's timing out for me on a slow connection. As you can see from the console output, it's timing out with

File "/usr/local/lib/python3.6/dist-packages/pipenv/utils.py", line 517, in resolve
    result = c.expect(u"\n", timeout=environments.PIPENV_INSTALL_TIMEOUT)`

Are you sure PIPENV_INSTALL_TIMEOUT doesn't play a part in creation of the Pipfile.lock file? If it doesn't, is there any way I can increase the timeout so that I can give pipenv lock more time on a slow connection?
