 *   PASSED_STEPS                  Steps passed to install components using Jenkins on CICD cluster: "salt,core,cicd,openstack:3200,stacklight:2400",
                                   where 3200 and 2400 might be timeouts (not used in the testing pipeline)
 *   RUN_TEST_OPTS                 Pytest option -k or -m, with expression to select necessary tests. Additional pytest options are allowed.
