Error message when Semeru is deployed on non-OCP without Cert Manager

[leochr]

To use Semeru on non-OCP cluster, Cert Manager must be installed. The error message that's output (APIVersion is not available) is not clear enough to provide guidance to the user on what to do. Handle the error by adding a message with the action the user should take to resolve the error:
