      Description of problem:

      OCP upgrade blocks because of cluster operator csi-snapshot-controller fails to start its deployment with a fatal message of read-only filesystem

      Version-Release number of selected component (if applicable):

      Red Hat OpenShift 4.11
rhacs-operator.v3.72.1

      How reproducible:

      At least once in user's cluster while upgrading

      Steps to Reproduce:

      1. Have a OCP 4.11 installed
2. Install ACS on top of the OCP cluster
3. Upgrade OCP to the next z-stream version

      Actual results:

      Upgrade gets blocked: waiting on csi-snapshot-controller

      Expected results:

      Upgrade should succeed

      Additional info:

      stackrox SCCs (stackrox-admission-control, stackrox-collector and stackrox-sensor) contain the `readOnlyRootFilesystem` set to `true`, if not explicitly defined/requested, other Pods might receive this SCC which will make the deployment to fail with a `read-only filesystem` message
