PD CSI Driver xref: kubernetes-sigs/gcp-compute-persistent-disk-csi-driver#361
Fixes: kubernetes-sigs/gcp-compute-persistent-disk-csi-driver#360

/assign @msau42 @jsafrane

/kind bug

looks good to me too! we already do this for AWS and on AWS in fact we leave more than one disk to account for boot disk and may be disk for docker setup. many installations that use overlay2 prefer their own disk for docker
