This significantly reduces the surface area of the fieldmanager package
by hiding all the private "managers" objects, as well as the interface
that was made specifically for these. There is no reason to configure
these.
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.
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

Ginkgo relies on all workers defining all tests in exactly the same order. This
wasn't guaranteed for these tests, with the result that some tests might have
been executed more than once and others not at all when running in parallel.
This was noticed when some of these tests started to flake and then were
reported both as failure and success, as if they had been retried.
It doesn't make sense for the E2E framework to have command line options that
don't do anything because then all test suites built with the framework inherit
those options.
For -list-images and -list-conformance-tests the solution is to move the
implementation into the framework (-list-images) respectively move the flag
into test/e2e (-list-conformance-tests).
The placement was decided based on the observation that image patching is
common functionality while conformance testing is specific to one test suite.
The "[sig-network] DNS HostNetwork should resolve DNS of partial qualified
names for services on hostNetwork pods with dnsPolicy:
ClusterFirstWithHostNet" test assumes that a service named "kube-dns"
exists in the "kube-system" namespace. This assumption is valid if the
cluster was configured using kubeadm, but the assumption may be invalid
otherwise.
As the test uses dnsPolicy: ClusterFirst (as opposed to dnsPolicy: None),
it does not need to specify the name server in dnsConfig. Omitting
dnsConfig.nameservers obviates the need to look up the service.
Follow-up to commit add4652352.
* test/e2e/network/dns.go: Don't look up or use the kube-dns cluster IP
address as it might not exist on clusters that were not configured using
kubeadm.
The old tests were no longer passing with Ginkgo v2.5.0. Instead of keeping the
old approach of checking recorded spec results, now the tests actually cover
what we care about most: the results recorded in JUnit.
This also gets rid of having to repeat the stack backtrace twice (once as part
of the output, once for the separate backtrace field).
