Checklist:

• I have performed a self-review of my own code to ensure there are no formatting, vetting, linting, or security issues
• I have verified that new and existing unit tests pass locally with my changes
• I have not allowed coverage numbers to degenerate (81.8%)
• I have maintained at least 90% code coverage
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• I have added tests that prove my fix is effective or that my feature works
• I have maintained backward compatibility (via Init Container which will migrate RG & CRD versions during upgrade. With that, existing RGs continue to work).

How Has This Been Tested?

• Installed CSM 1.5 replication module with isilon driver, and provisioned few PV/RGs.
• Upgraded isilon & replicator sidecar images to latest on both k8s clusters.
   cd dell-csi-helm-installer && ./csi-install.sh --namespace isilon --values /home/santhosh/my-samples/csm-replication/isilon-values.yaml --upgrade
• Upgraded replication-controller images.
   ./repctl create -f ../deploy/controller.yaml
• Verified RGs and CRD for v1 version with init container logs and kubectl on both clusters.
• Deleted target PowerScale SyncIQ policies.
• Restarted pod to confirm no migration was run second time.
• Provisioned new RG and ran replication actions on existing & new RGs.
