gluster-blockd: consider spare nodes to satisfy the multipath request
In case if number of block hosts are more than the multipath request,
consider that spare nodes to satify the request.
Lets say we need multipath of 3, but the admin provides 5 block-hosts.
If any of the node fail to configure target from first three, then
consider configuring fourth node to satify the HA request.
