doc: update doc for disaster recovery

Volume Replication has been added to csi-addons
as a feature in it sometime back. But the doc still
uses the volume replication operator to enable
mirroring and create related resources for
disaster recovery.
this commit updates the document to use csi-addons
instead of creating volumereplication sidecar.

-Volume Replication Operator is a kubernetes operator that provides common
- and reusable APIs for storage disaster recovery.
- It is based on [csi-addons/spec](https://github.com/csi-addons/spec)
- specification and can be used by any storage provider.

-Volume Replication Operator follows controller pattern and provides
- extended APIs for storage disaster recovery.
- The extended APIs are provided via Custom Resource Definition (CRD).
