Kevin Klues 462544d079 Split CPUManager takeByTopology() into two different algorithms ...

The first implements the original algorithm which packs CPUs onto NUMA nodes if
more than one NUMA node is required to satisfy the allocation. The second
disitributes CPUs across NUMA nodes if they can't all fit into one.

The "distributing" algorithm is currently a noop and just returns an error of
"unimplemented". A subsequent commit will add the logic to implement this
algorithm according to KEP 2902:
