    cluster/ec: return all node uuids from all subvolumes

    EC was retuning the UUID of the brick with smaller value. This had
    the side effect of not evenly balancing the load between bricks on
    rebalance operations.

    This patch modifies the common functions that combine multiple subvolume
    values into a single result to take into account the subvolume order
    and, optionally, other subvolumes that could be damaged.

    This makes easier to add future features where brick order is important.
    It also makes possible to easily identify the originating brick of each
    answer, in case some brick will have an special meaning in the future.
