Describe use cases (node IDs, HT siblings, etc)
Call out novelty (Linux CPU list parse/dump)
Describe future work (relax immutable, refactor to use 'set')
All usage of builder pattern is convertible to cpuset.New()
with the same or fewer lines of code.
Migrate Builder.Add to a private method of CPUSet, with a comment
that it is only intended for internal use to preserve immutable
propoerty of the exported interface.
This also removes 'require' library dependency, which avoids
non-standard library usage.
FilterNot is only used in this file, and is trivially converted to a
'filter' call site by inverting the predicate.
Filter is only used in this file, so don't export it.
In 'set', conversions to slice are done also, but with different names:
ToSliceNoSort() -> UnsortedList()
ToSlice() -> List()
Reimplement List() in terms of UnsortedList to save some duplication.
Removes exit/fatal from cpuset library.
Usage in podresources test was not necessary.
Library reference in cpu_manager_test was moved to a local function, and
converted to use e2e test framework error catching.
Before, in RunPostFilterPlugins, we didn't distinguish between unschedulable and unresolvable
because we only have one postFilterPlugin by default, now, we have at least two, we should
make sure that once a postFilterPlugin returns unresolvable, we'll return directly

This is an ugly-but-simple rewrite (particularly involving having to
rewrite "single Endpoints with multiple Subsets" as "multiple
EndpointSlices"). Can be cleaned up more later...
The slice code sorts the results slightly differently from the old
code in two cases, and it was simpler to just reorder the expectations
rather than fixing the comparison code. But other than that, the
expected results are exactly the same as before.
This exposed a bug in the EndpointSlice tracking code, which is that
we didn't properly reset the "last change time" when a slice was
deleted. (This means kube-proxy would report an erroneous value in the
"endpoint programming time" metric if a service was added/updated,
then deleted before kube-proxy processed the add/update, then later
added again.)
In the dual-stack case, iptables.NewDualStackProxier and
ipvs.NewDualStackProxier filtered the nodeport addresses values by IP
family before creating the single-stack proxiers. But in the
single-stack case, the kube-proxy startup code just passed the value
to the single-stack proxiers without validation, so they had to
re-check it themselves. Fix that.
Before, the return type of RunFilterPlugins is a Map, but considering we'll return immediately
once we met unsuccessful status, this is not necessary.

TestEndpointsToEndpointsMap tested code that only ran when using
Endpoints tracking rather than EndpointSlice tracking--which is to
say, never, any more. (TestEndpointsMapFromESC in
endpointslicecache_test.go is an equivalent EndpointSlice test.)
