Make hroller also plan for non-redundant instances

Non-redundant instances need to be moved to a different node
before maintenance of the node. Even though they can be moved to
any node, there must be enough capacity to host the instances of the
reboot group to be evacuated.

This is achieved by greedily moving the non-redundant instances
to other nodes, till we run out of capacity. In this way we
refine the groups obtained by coloring the drbd-induced graph.
