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.
