Fix endurance failures

- endurance test failed since it exited with 'Unsucessful' termination
  because teardown.sh  was not able to remove CPS images (cps-and-nmcp,
policy-executor-stub). The tag 'latest' was used for both pipelines at
the same time: Regular KPI and Endurance
- teardown algorithm changed: it only remove cps images having 'Snapshot' tag.
- dmi-stub removed from the image list since it should always use the
  Snapshot version in the deployment!
