f8511877e2 Add regression test for CPUManager distribute NUMA algorithm 
We witnessed this exact allocation attempt in a live cluster and witnessed the
algorithm fail with an accounting error. This test was added to verify that
this case is now handled by the updates to the algorithm and that we don't
regress from it in the future.

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.

547996f3f6 cpumanager: test NUMA node support for CPU assign (1) 
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.

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.
