For each pnf_macro test simulator is created using MSB K8S API. Sometimes test fails because the simulator creation error. Error log message is:

2021-07-28 05:12:22,711 ERROR 233:onap_service.py(1) - [None][Create Instance] request failed: Code: 500. Info: Create Kubernetes Resources: Error creating kind: /v1, Kind=Service: Error in plugin Service plugin: Create Service error: services "pnf-macro-test-simulator-mongo" already exists
.

It looks like the simulator is not removed properly and/or onap namespace is not cleaned properly before tests start
