[PATCH manager 11/13] pvestatd: broadcast multipath map health to the cluster

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

Publish this node's per-WWID map health into the cluster KV store on
each status loop, so the datacenter-wide health matrix can combine it
without querying every node live. The helper clears the key when this
node is not multipathing, keeping the matrix scoped to the active
nodes. Guarded and self-contained like the nearby config sync.
