Pod stuck in `ContainerCreating` state in k8 1.12.3

[surbhibakhtiyar]

While creating pod using this driver it gives the following error :

  Warning  FailedMount  6s (x5 over 14s)  kubelet, 10.xx.xx.xx  MountVolume.SetUp failed for volume "test" : invalid character '/' looking for beginning of value

The same script docker-flexvol.sh works fine with k8 1.10.11 but not 1.12.3

@surbhibakhtiyar i tried the steps outlined in README.md against latest kubernetes and i don't see the issue. Can you please try the exact same steps as in the readme including the my-container-image container and let me know please?

@surbhibakhtiyar can you check the kubelet logs (on the node where the failure occurs) and look for the same error (and look if there are any more information just before this problem occurs?)
