Remove pipenv dependency

pipenv is really slow and sometimes it hangs for a really long time.
Perhaps because I'm using a private PyPi instance that makes it worse,
but that works fine with plain pip.

This seems to be a common problem - see and the several other linked
issues there:

pypa/pipenv#3827

So far, this is just the result of grep/search/replace. Haven't
tested this at all and there's more work to do. Just want to start by getting
some feedback if this is going to be something that everyone is OK with.

Closes hashicorp#324
