'shade is required for this module' error when provisioning openstack from venv

[samvarankashyap]

Note for future reference :
When using ansible playbooks in a virtual environment .
ansible_python_interpreter variable needs to be set in ansible.cfg or hosts file as follows

ansible_python_interpreter="/usr/bin/env python"

PR #72 fixes the issue

I don't think adding shade to the requirements.txt resolves this issue.

I've got shade installed inside the virtualenv.

Outside the venv, you can see that shade isn't installed

I think the problem might be that I don't have linch-pin checked out into the venv. I didn't do this previously, however, and it worked just fine. That was, a centos 7.2 system, however. This one is fedora 23 x86_64.
