Enables improved discovery of mounted volumes during kubelet startup. Since this code has been significantly refactored, we allow to opt-out in case kubelet gets stuck at the startup or is not unmounting volumes from terminated Pods. Note that this refactoring was behind SELinuxMountReadWriteOncePod alpha feature gate in Kubernetes 1.25.

Before Kubernetes v1.25, the kubelet used different default behavior for discovering mounted volumes during the kubelet startup. If you disable this feature gate (it's enabled by default), you select the legacy discovery behavior.

In Kubernetes v1.25 and v1.26, this behavior toggle was part of the SELinuxMountReadWriteOncePod feature gate.
