[PATCH cluster 08/13] pmxcfs: track cluster-wide multipath configuration

[Thomas Lamprecht <t.lamprecht@proxmox.com>]

pve-storage registers two cluster-wide files via cfs_register_file: the
managed /etc/pve/multipath.cfg (the WWID allow-list plus the global and
per-LUN multipathd knobs) and /etc/pve/multipath-overrides.conf for the
free-form, admin-owned hardware override sections. Both need to be
observed and tracked for change notification, so they are replicated
across the cluster and consumers are notified on change.
