keystone ci: Start working on initial population of sample data.

Still WIP. Basing this off of:

    http://docs.openstack.org/developer/keystone/developing.html#initial-sample-data

But the sample config file doesn't seem to result in listening on port
5000, and openstackclient (with those environment variables) seems to
expect it to. Initial setup seems to work, but then we can't actually
talk to the endpoint.
