Description of problem:
csi-attacher image for 3.10 using api group storage.k8s.io/v1alpha1 to get VolumeAttachment resource

Version-Release number of selected component (if applicable):
oc v3.10.0-0.21.0
openshift v3.10.0-0.21.0
kubernetes v1.10.0+b81c8f8
# oc exec csi-hostpath-plugin  -c external-attacher -- rpm -qa|grep csi
csi-attacher-0.2.0-1.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Create csi Pod using hostpath driver
2. Create sc for csi hostpath driver
3. Create a PVC to claim storage from csi hostpath driver
4. Create a Pod using the PVC

Actual results:
Pod can not get ready and report:
