Updated requirements -- READ THIS FIRST!

Requirements changed to run libcloud 0.14.0-beta3

In order to comply, we must change the AUTH_URL of openstack clients
from $SERVER/v2.0 --> $SERVER/v2.0/tokens

We must also update rtwo to 0.1.8-dev2 to handle the new auth urls
because they are not accepted by the openstack user and network clients.

To do this from the shell:
>>> from core.models import Provider
>>> os = Provider.objects.get(location='OPENSTACK')
>>> auth_url = os.providercredential_set.get(key='auth_url')
>>> auth_url.value = '%s/tokens' % auth_url.value
>>> auth_url.save()

You should also update your atmosphere settings/secrets.py code
to reflect the new change
