Restrict instance moves in hroller to the same node group

When scheduling rolling reboots, hroller looks for nodes to evacuate
the non-redundant instances to. This is done by greedily moving
instances to other nodes that can take them, policy wise and capacity
wise. There is, however, another restriction to be taken into account:
instances should only be moved within a node group. This is achieved
by this patch.
