core: util for removing overlaps in ranges

user defined MacPool ranges can contain overlaps. Previously this was
handled by adding each MAC from each mac range into HashSet. This was
inefficient and can cause lot of MACs being initialized pointlessly.
This util takes N ranges and transform it into M ranges (M<=N) where
are no overlaps.
