deploy: update external-provisioner to v2.1.1

This brings in some bug fixes:

- External-provisioner may have stopped provisioning for a PVC depending on certain timing conditions (provisioning failed once, next attempt currently running, PVC update arrives from API server)
- Fix CSI translation issues with EBS, AzureFile and Cinder drivers
- Producing storage capacity may have failed with the object has been modified errors
- Fix topology translation during CSI migration for gce-pd, aws-ebs, cinder drivers
