Expand the Node Loss section in block-storage.md to accurately describe the automatic fencing flow, and add dedicated Network Fencing sections across the CSI documentation to provide configuration examples for both manifest-based and Helm-based deployments.
* block-storage.md: introduce the Network Fencing prerequisite paragraph with links to the new example sections, replace the single-line "auto-fencing" description with three bullets describing the client blocklist flow, and update Node Recovery to a single sentence covering workload rescheduling and the 5-minute cool-down behavior that triggers automatic unblocklist. Add a Warning admonition instructing administrators not to remove the out-of-service taint before the node completes a full power cycle.
* csi-configuration.md: add a Network Fencing section enumerating the three prerequisites (CSI-Addons controller, CSI-Addons sidecar, enableFencing flag) and showing the RBD Driver CR manifest with deployCsiAddons and enableFencing set together.
* csi-drivers-chart.md: add a Network Fencing subsection under Custom settings showing the per-driver Helm values for deployCsiAddons and enableFencing, with a cross-reference to csi-configuration.md.
* ceph-csi-drivers.md: replace the legacy CSI_ENABLE_CSIADDONS configmap patch in the Enable CSI-Addons Sidecar section with the modern deployCsiAddons approach on OperatorConfig or Driver, and add a Network Fencing overview section that links out for configuration details and the operational flow.

Updated the required documentation and yamls
where we are adding support for the QoS for
the rbd pvc that uses the krbd mounter.

since ceph-csi driver now handles both rbd and cephfs
volume node loss case, let's remove rbd specific
wording from the node loss doc in rook.

with latest design for networkFence, no need for
csi-addons to be installed as the implementation
is moved to csi-drivers.

updating the csi operator API version
to latest version.
Adding the cephFS and RBD controllerPublish
secret that are required for the fencing
operation that is supported by ceph-csi
with csi-operator.
Updated the storageclass to include the
secrets incase if user wants to override
the defaults in the clientProfile for
new PVC's.

Add formatting to some namespace names and provisioner values in order
to make the
Storage-Configuration/Block-Storage-RBD/block-storage/provision-storage
section more legible.

Disabling the RBD and CephFS fencing
in Rook for now as its having bugs where
Rook is blocklisting wrong IP address
due to timing issues.

in the existing node watcher, we'll check for node update
event and see if there are `out-of-service` taints are applied
and `ROOK_WATCH_FOR_NODE_FAILURE` is enabled in rook-ceph-operator-configmap,
if then we'll create the networkFence cr and delete the cr if nodes come back.
And, added the unit test too.
