New global scope argocdServer section for values-global.yaml

- Added new section for to configure the ArgoCD server to support tls
  argocdServer:
    route:
      tls:
        insecureEdgeTerminationPolicy: Redirect
        termination: reencrypt
- Default for ArgoCD is to create route with the following:
      route: enabled
      tls:
        insecureEdgeTerminationPolicy: Redirect
        termination: passthrough

    For more information please refer to https://issues.redhat.com/browse/GITOPS-3918.
