Description of problem:
Manila csi storage can not be used on the SSC OSP16 cluster

Version-Release number of selected component (if applicable):
4.6.0-0.nightly-2020-09-26-202331

How reproducible:
Always

Steps to Reproduce:
1. Install an OCP cluster on a ssc OSP16 cluster
2. Create PVC with manila csi sc
3. Create a Pod using this PVC

Actual results:
Pod can not be run successfully

  Warning  FailedMount  <invalid> (x2 over 110s)    kubelet            Unable to attach or mount volumes: unmounted volumes=[local], unattached volumes=[local default-token-86269]: timed out waiting for the condition

Expected results:
Pod can be run successfully.
