to keep a count of the pods that have the ready condition.
Also:
- Add feature gate JobReadyPods.
- Add Ready to describe.

This parameter ensures that CPUs are always allocated in groups of size
'cpuGroupSize'. This is important, for example, to ensure that all CPUs (i.e.
hyperthreads) from the same core are handed out together.

As part of this, pull out all of the existing "TakeByTopology" tests and have
them be called by the original TestTakeByTopologyNUMAPacked() as well as the
new TestTakeByTopologyNUMADistributed() test. In a subsequent commit, we will
add some tests that should differ between these two 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:

Enable feature by default.
Update integration tests for other features to assume that finalizers are present.

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.

The exisiting unit tests where performing subtests without
actually using the full features of the testing package
(https://pkg.go.dev/testing#hdr-Subtests_and_Sub_benchmarks)
Update them with fairly minimal changes. The patch is deceptively
large because we need to move the code inside a new block.

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.

This allows us to get rid of the check for determining which one is higher all
throughout the code. Now we just check once and instantiate an interface of the
appropriate type that makes sure the ordering in the hierarchy is preserved
through the appropriate calls.
