cluster/afr: Return the list of node_uuids for the subvolume
Problem:
AFR was returning the node uuid of the first node for every file if
the replica set was healthy, which was resulting in only one node
migrating all the files.
Fix:
With this patch AFR returns the list of node_uuids to the upper layer,
so that they can decide on which node to migrate which files, resulting
in improved performance. Ordering of node uuids will be maintained based
on the ordering of the bricks. If a brick is down, then the node uuid
for that will be set to all zeros.
