[PATCH manager 09/13] pvestatd: apply the cluster-wide multipath config on each node

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

Write out the cluster-wide multipath.cfg on each node once per status
loop: build the local multipathd drop-ins and reload multipathd when
they change. The work is a cheap no-op unless multipath is in use, and
the logic is kept out of pvestatd itself, so this is just a thin
trigger.
