Misleading warning and error reported at the end of a test run
When I execute a test case via ocs-ci, at the and of the log I see the following lines:

```
16:30:45 - MainThread - ocs_ci.ocs.ocp - WARNING - Failed to get resource: namespace-test-47b4cf16197941bd9a004243ae8deea6 of kind: Project, selector: None, Error: Error during execution of command: oc -n namespace-test-47b4cf16197941bd9a004243ae8deea6 --kubeconfig /home/ocsqe/data/cluster-2020-01-21.1/auth/kubeconfig get Project namespace-test-47b4cf16197941bd9a004243ae8deea6 -n namespace-test-47b4cf16197941bd9a004243ae8deea6 -o yaml.
Error is Error from server (NotFound): namespaces "namespace-test-47b4cf16197941bd9a004243ae8deea6" not found

16:30:45 - MainThread - ocs_ci.ocs.ocp - ERROR - Number of attempts to get resource reached!
16:30:45 - MainThread - ocs_ci.ocs.ocp - INFO - Project namespace-test-47b4cf16197941bd9a004243ae8deea6 got deleted successfully
```

Reporting a warning and an error because the namespace which is being deleted during the teardown is misleading. The code should not report error for an expected outcome. This increases a cost of debugging when something actually goes wrong.
