cephfs: add controller sidecar for setting CSI metadata on subvolumes

iPraveenParihar · iPraveenParihar · commit eec424595631 · 2026-03-26T19:02:00.000+05:30
Add the csi-cephfsplugin-controller sidecar container to the CephFS
controller plugin deployment, gated by the GenerateOMapInfo field.
This mirrors the upstream ceph-csi change that adds support for
setting CSI metadata (PV/PVC info) on CephFS subvolumes.
