This patch adds swift scenarios, cleanup resource, and unit tests.

Swift Scenarios:
- create_container_and_object_then_list_objects
- create_container_and_object_then_delete_object
- create_container_and_object_then_download_object

Blueprint benchmark-scenarios-for-swift

This patch also fixed a minor bug with osclients.py where incorrect
"authurl" param name was used.
