Firecloud installation is broken with the latest setuptools==50.0.0.

I'm getting this on all versions:

easy_install is deprecated and they finally removed it: https://setuptools.readthedocs.io/en/latest/easy_install.html

To reproduce, run:

pip install setuptools==50.0.0 && pip uninstall firecloud && pip install --no-cache firecloud

I've posted a fix: #148 Hopefully someone will get some time to review it.
