install requirements_test.txt on dev boxes

[binary1230]

Currently, to run the unit tests directly without running through tox.ini (through pycharm, for instance), we need to run pip install -r requirements_test.txt

What we should do is check if dev_box is set to true in the puppet config, and then add a line that runs pip install -r requirements_test.txt in https://github.com/magfest/ubersystem-puppet/blob/master/manifests/install_dependencies.pp#L6

Was this fixed by: magfest-archive/simple-rams-deploy#30?

nah, seperate issue.

I can run the tests from pycharm now (with a little weirdness but correct result), however, I had to do a workaround of manually installing the stuff in requirements_test.txt. Puppet should do that if dev_box is true.

I'm getting some other odd issues running unit tests locally under vagrant+windows related to sqllite, will post those later.

Yeah, we've really grown beyond the capabilities of SQLite. Our tests are just barely holding together running against SQLite, which is why I opened this issue: magfest/ubersystem#2517
