One test creates a stack with a tag, updates the tag and then deletes the tag. The second test, creates a stack with a tag named 'hidden'. In heat.conf, hidden_stack_tags is set to 'hidden' which means whichever stack has a tag named 'hidden', stack.list() should not pick it up. blueprint stack-tags Change-Id: Idf6669ccf5e210d4e6da3733a9ac190418306d98
