As a technical debt this change replaces "heat stack-show" with "openstack stack show" as well as "heat stack-delete" with "openstack stack delete" to remove deprecation warnings such as 'WARNING (shell) "heat stack-show" is deprecated, please use "openstack stack show"' Change-Id: I7bcc18445f3263128a9bff29a057f172af143c90
