As a Cloud Pak I want to request a CommonService CR through an operandrequest

Details

As a Cloud Pak that has adopted the use of ODLM to manage its resources, I want to configure and deploy a local CommonService CR through ODLM to be reconciled by ibm-common-services with the base resource (resides in ibm-common-services namespace by default).

The Cloud Pak has a Lead operator and a handful of Component operators. There is no Capability operator layer at this time.
As such, the Lead operator could be thought of also as a capability operator itself. In order to provide a design that allows for seamless transition between the various Lead and Capability topologies and entry points, we would like to utilize ODLM to manage the request for the local CommonService resource.

If we add the ibm-common-service-operator into the common-service OperandRegistry, we could actually create the CommonService CR byOperandRequest through this new feature.
https://github.com/IBM/operand-deployment-lifecycle-manager/blob/master/docs/design/create-cr-by-operandrequest.md

The below example will create the CommonService CR in cloud-pak1 namespace,

apiVersion: operator.ibm.com/v1alpha1
kind: OperandRequest
metadata:
  name: CS-instance
  namespace: cloud-pak1
spec:
  requests:
  - registry: common-service
    registryNamespace: ibm-common-services
    operands:
    - name: ibm-common-service-operator
      kind: CommonService
      apiVersion: operator.ibm.com/v3
      instanceName: common-service
      spec:
        size: small

@horis233 Please correct me if I am wrong.
