[WIP] Decouple OperandConfig controller from OLM

[bluzarraga]

What this PR does / why we need it: CPD testing of argoCD based deployments on CNCF clusters were blocked due to the error in the first comment found repeating in the ODLM logs. This signaled that the operandconfig controller was not completely decoupled from OLM based on its reliance on finding the subscription and csv for an operator in order to update the operandconfig status. I more or less mirrored the changes to the operandrequest controller by shifting focus from sub and csv to deployment. There is less to update in operandconfig than there was in operandrequest so I am not as sure about having a totally separate controller again but that was the my best bet given the time. Open to suggestions for improvement.
