      Epic Goal

      Support upstream feature "New RWO access mode [Add E2E Tests]"" in OCP as Beta, i.e. test it and have docs for it (unless it's Alpha upstream).

      Summary: PV/PVCs get new AccessMode, ReadWriteOncePod. This means that such PV/PVC can be used only in a single pod on a single node. Compare with existing ReadWriteOnce AccessMode, where such a PV/PVC can be used on a single node by many pods. We need to update our AccessMode docs (but there is not much today). 

      Why is this important?

      • We get this upstream feature through Kubernetes rebase. We should ensure it works well in OCP and we have docs for it.

      Acceptance Criteria

      • CI - MUST be running successfully with tests automated

      • ...

      Dependencies (internal and external)

      1. External: the feature is currently scheduled for Beta in Kubernetes 1.27, i.e. OCP 4.14, but it may change before Kubernetes 1.27 GA.
