OpenStack cleanup script

This is needed in case any test case doesn't clean what it creates in openstack.
(This has been happening sometimes for Tempest, for example)

This script will remove:
- nova instances
- glance images
- cinder volumes
- networks/subnets/ports
- routers
- floating ips
- security groups
- users and tenants (not admin)

It won't remove the defaults.
