As a user, I want to install GitOps Operator on OCP for the first time and the default Argo CD instance should automatically install/enable RHSSO.   However, I do not want RHSSO to be automatically installed to the existing default instance if I upgrade GitOps Operator.   In that case, I can enable SSO on the default Argo CD instance after upgrading GitOps Operator by setting the SSO flag in the ArgoCD CR.

Acceptance Criteria

• After installing GitOps Operator the first time (i.e. not upgrading), RHSSO ins automatically enabled on the default Arigo CD instance
• After upgrading GitOps Operator, the default ArgoCd instance should not be enabled with SSO automatically.
• After upgrading GitOps Operator, I can enable RHSSO on the default ArgoCD instance by setting the SSO flag in the ArgoCD CR.
• Add unit tests.
