Erroneous collecting "clusterversion" In case of openshift distribution #133
Description
Good day!
I've tried to deploy Cerberus with distribution config "openshift" and faced the following issue:
2021-05-05 14:24:45,635 [INFO] Starting ceberus

Could you please clarify for what purpose start_cerberus.py tries to get some resource with the name clusterversion using kubectl?

Unfortunately, I cannot find any details about the command kubectl get clusterversion and the resource clusterversion.
As a temporary solution, I just switched off this if statement.
