Epic Goal

Support upstream feature "NodeExpansion secret"" in OCP as GA, i.e. test it and have docs for it.

This is continuation of STOR-1172. This is yet another feature of CSi that is useful only for CSi driver vendors. It has very limited visibility to end users.

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.

Dependencies (internal and external)

1. External: the feature is currently scheduled for GA in Kubernetes 1.29, i.e. OCP 4.16, but it may change before Kubernetes 1.29 GA.
