The caller in openstackclient/object/v1/object.py passed a keyword
argument full_listing, but the eventual callee container_list()
expected all_data. So, --all did not work at all.
The issue passed undetected because --all did not have a test,
so we added a unit test.
In addition, exisiting tests were using a test set that did
not look like the real container listing, so we changed
LIST_CONTAINER_RESP to be realistic.
