* Added support for immediate block storage provisioning
  - Already exists in ec2 module
  - Syntax is the same as for ec2 module

       volumes:
         - display_name: vm1-vol1
           device_name: /dev/vdb
           volume_size: 10
           delete_on_termination: true

  - delete_on_ternmination is not an openstack feature
    but will work during delettion

* Changed the authentication to Password() method
  - Reflects most recent documentation
  - Necessary to switch between compute and volume
    actions if API URLs for those are different,
    which is true for a lot of installations
