4bae656835 cpumanager: test NUMA node support for CPU assign (2)
This batch of tests adds a fake topology on which each numa node
has multiple sockets. We didn't find yet a real HW topology in the wild
like this, but we need one to fully exercise the code.

So, until we find a HW topology, we add a fake one flipping
the NUMA/socket config of the existing xeon dual gold 6320.

This batch of tests adds a real topology on which each physical socket
has multiple NUMA zones. Taken by a real dual xeon 6320 gold.

15caa134b2 cpumanager: topology: use rich cmp package
User the `cmp.Diff` package in the unit tests, moving away from
`reflect.DeepEqual`. This gives us a clearer picture of the differences
when the tests fail.

a047e8aa1b move to cadvisor.MachineInfo
This patch removes GetNUMANodeInfo, cadvisor.MachineInfo will be used
instead of it. GetNUMANodeInfo was introduced due to difference of meaning of
MachineInfo.Topology. On the arm it was NUMA nodes, but on the x86 it
represents sockets (since reading from /proc/cpuinfo). Now it unified
and MachineInfo.Topology represents NUMA node.

ecc14fe661 Update CPUManager to include NUMANodeID in CPUTopology
Unfortunately, the NUMA information is not readily available from
cadvisor, so we have to roll the logic to discover it by hand. In the
future, we should remove this custiom code to use the information
provided by cadvisor once it is made available.
