If the client immediately closes connection after SCTP handshake,
the server will die with EOF, adding send and recv calls in the
client to make sure server client handling loop exits gracefully.

If the client immediately closes connection after SCTP handshake, the
remote-addr fetched by SCTP server can be nil, causing the server to crash.

agnhost was updated to v2.46 in PR 123258, but the image was not
published due to the failue of `post-kubernetes-push-e2e-agnhost-test-images`
(issue 123266).

Merge vishh/stress@eab4e3384b into
agnhost.
Old usage: `stress -mem-alloc-size 12Mi -mem-alloc-sleep 10s -mem-total 4Gi`
New usage: `agnhost stress --mem-alloc-size 12Mi --mem-alloc-sleep 10s --mem-total 4Gi`
This is a part of the steps to migrate from legacy Schema 1 images
(issue 123146)

add a new functionality to the agnhost image to run a server that
closes the connections received by sending a RST.
If a TCP servers closes the connection before all the socket is read,
it sends a RST. This implementations just reads only one byte from the
connection and closes it after that, that means that in order for this
to work the client has to send at least 2 bytes of data.
Using a simple curl is enough to trigger a RST:
curl http://127.0.0.1:8080
curl: (56) Recv failure: Connection reset by peer

It wasn't documented that InitLogs already uses the log flush frequency, so
some commands have called it before parsing (for example, kubectl in the
original code for logs.go). The flag never had an effect in such commands.
Fixing this turned into a major refactoring of how commands set up flags and
run their Cobra command:
- component-base/logs: implicitely registering flags during package init is an
anti-pattern that makes it impossible to use the package in commands which
want full control over their command line. Logging flags must be added
explicitly now, something that the new cli.Run does automatically.
- component-base/logs: AddFlags would have crashed in kubectl-convert if it
had been called because it relied on the global pflag.CommandLine. This
has been fixed and kubectl-convert now has the same --log-flush-frequency
flag as other commands.
- component-base/logs/testinit: an exception are tests where flag.CommandLine has
to be used. This new package can be imported to add flags to that
once per test program.
- Normalization of the klog command line flags was inconsistent. Some commands
unintentionally didn't normalize to the recommended format with hyphens. This
gets fixed for sample programs, but not for production programs because
it would be a breaking change.
This refactoring has the following user-visible effects:
- The validation error for `go run ./cmd/kube-apiserver --logging-format=json
--add-dir-header` now references `add-dir-header` instead of `add_dir_header`.
- `staging/src/k8s.io/cloud-provider/sample` uses flags with hyphen instead of
underscore.
- `--log-flush-frequency` is not listed anymore in the --logging-format flag's
`non-default formats don't honor these flags` usage text because it will also
work for non-default formats once it is needed.
- `cmd/kubelet`: the description of `--logging-format` uses hyphens instead of
underscores for the flags, which now matches what the command is using.
- `staging/src/k8s.io/component-base/logs/example/cmd`: added logging flags.
- `apiextensions-apiserver` no longer prints a useless stack trace for `main`
when command line parsing raises an error.
There are some tests that doesn't need the UDP listener, so they
can disable it.
This is specially needed for tests that use hostNetwork pods, if 2
pods try to bind to the same port, the test will fail because one
of the pod can't be scheduled because of the port conflict.
To keep backwards compatibility, we can add an option to disable
the UDP listener by setting the port number to -1, that is consistent
with the SCTP implementation.
The Container Images for Windows Server 2022 have been published, and
we can start building test images using them, so we can start adding
jobs for them.
The image versions for the e2e test images have been bumped in a previous
commit, but haven't been promoted yet. We don't need to bump them here.
httpd-2.4.46-win64-VC15.zip no longer exists, so we have to use
httpd-2.4.48-win64-VC15.zip instead.
