Upstream Cinder CSI Plugin changes

[Cory Johns]

The external provider for OpenStack was recently updated[1] with changes that alter the provider field value of the storage class, changing it from "csi-cinderplugin" to "cinder.csi.openstack.org".

We currently pin the revision in the cloud-provider-openstack repo, and the manifests are properly versioned, so this won't cause any breakage, but we should update cdk-addons to follow upstream.

In relation to this, is it okay that under kubernetes 1.16 we are using the v1.15.0 cinder-csi-plugin image?

        - name: cinder-csi-plugin
          image: {{ registry|default('docker.io') }}/k8scloudprovider/cinder-csi-plugin:v1.15.0

The upstream changes in versions was for the first three pods from 1.0.1 to 1.2.0, but I don't see the referenced commit changing the rev of the cinder-csi-plugin image.

After restarting the pod we were having issues with, the 1.15.0 csi-cinder driver does work with kubernetes 1.16.0.
