Allow insecure auth via keystoneclient

[Kieran Spear]

Keystoneclient (on pypi) now supports the 'insecure' keyword argument so we can pass through the value of OPENSTACK_SSL_NO_VERIFY from settings.py.

This allows connecting to servers with self-signed or otherwise invalid certificates for testing purposes.
