      Currently, vmware-vsphere-csi-driver-webhook exposes HTTP/2 endpoints:
      
      $ oc -n openshift-cluster-csi-drivers exec deployment/vmware-vsphere-csi-driver-webhook -- curl -kv   https://localhost:8443/readyz
      
      ...
      * ALPN, server accepted to use h2
      > GET /readyz HTTP/2
      < HTTP/2 404
