1. Proposed title of this feature request
Allow external provisioner to resume operations after being down.

2. What is the nature and description of the request?
The RFE is a follow up to BZ https://bugzilla.redhat.com/show_bug.cgi?id=1990428
Upstream issue: https://github.com/kubernetes-csi/external-provisioner/issues/486

The following scenario highlights the issue that needs to be solved

1. external-provisioner issues a CreateVolume call for a PVC
2. external-provisioner is stopped before it creates the PV
3. the PVC is deleted
4. external-provisioner is restarted

That volume provisioning started is not recorded anywhere, so the restarted external-provisioner doesn't know that it needs to continue with it.

3. Why does the customer need this? (List the business requirements here)

Customer can end up in a situation where the PVC is deleted but the PV is not.

4. List any affected packages or components.
