kube-proxy does not look at Endpoints ever, so it is incorrect for a
test to assume that there is any correlation between whether Endpoints
exist and whether a Service is working. Tests should only be using the
v1.Endpoints API if they are explicitly testing the behavior of
v1.Endpoints, the Endpoints controller, or the EndpointSlice mirroring
controller. There is no reason for any non SIG Network tests to be
testing any of those things, so there should be no references to
v1.Endpoints in test/e2e outside of test/e2e/network.
Also, simplify some pointlessly complicated e2eservice code.
This was previously used by some autoscaling tests that have since
been removed. It is somewhat sketchy (and inherently [Disruptive]),
and depends on iptables (so would need to be updated to use nftables
at some point if we were keeping it). Given that it's now unused, just
remove it (as well as some helper functions that are no longer used by
anyone else as well).
What happens at the moment in e.g. pull-kubernetes-e2e-kind in case of a
timeout is that ginkgo-e2e.sh gets killed with SIGTERM. This is not propagated
to the E2E test suite processes, therefore there is no "Interrupted by User"
report and no JUnit file, depending on timing during the process shutdown.
Running the Ginkgo CLI with job control enabled creates a new process group,
which then can be used to kill the Ginko CLI and the E2E test suite
processes. With these changes, more information is produced. Some of it seems
a bit redundant, but it's better than none:
*** hack/ginkgo-e2e.sh: received termination signal -> asking Ginkgo to stop.
***
*** Beware that a timeout may have been caused by some earlier test,
*** not necessarily the one which gets interrupted now.
*** See the "Spec runtime" for information about how long the
*** interrupted test was running.

First interrupt received; Ginkgo will run any cleanup and reporting nodes but will skip all remaining specs. Interrupt again to skip cleanup.
