[4.5] Deploy CNPG operator, config EDB server and create tls certificate CR

[YCShen1010]

Context:

• ODLM create common-service-postgresql operator and EDB cluster CR
  ticket: https://github.ibm.com/IBMPrivateCloud/roadmap/issues/62064

• ODLM creates certificate CR for the EDB sever and client authentication
  ticket: https://github.ibm.com/ibmprivatecloud/roadmap/issues/62065

How to test

1. Deploy Cert-Manager
2. As release 4.5 build is not ready, we could deploy 4.4 operator instead and update the OperandRegistry and OperandConfig with new entries.
3. Create an OperandRequest to request common-service-postgresql

   Kind: OperandRequest
   apiVersion: operator.ibm.com/v1alpha1
   metadata:
     name: <ibm-service-request>
   spec:
     requests:
       - operands:
           - name: common-service-postgresql
         registry: common-service
         registryNamespace: <foundational service operand namespace>
   

Observe

1. Subscription common-service-postgresql is created
2. EDB cluster CR common-service-db is ready
3. two certs common-service-db-replica-tls-cert and common-service-db-tls-cert are created by ODLM
4. related secrets are created by Cert-Manger
5. After the above steps are done, the server pod common-service-db-1 is running.
