Description of problem:
Every 10 seconds on each node the kubelet logs this error:

It seems there is some functionality the kubelet is expecting in cri-o that does not yet exist.

Version-Release number of selected component (if applicable):
cri-o-1.0.0.alpha.0-1.git91977d3.el7
containernetworking-plugins-0.5.2-2.el7

How reproducible:
Always


Steps to Reproduce:
1. Set up OpenShift cluster using CRI-O
2. Check journalctl


Actual results:
Kubelet complains that it is unable to get filesystem info from the "remote"/cri-o runtime.


Expected results:
Kubelet should be able to retrieve the filesystem information it is looking for
