In 1.24 kubeadm will:
- stop using the "master" label on CP nodes.
- start tainting CP nodes with both "master" and "control-plane" taints.
In 1.25 the "master" taint will be removed.
Adjust references of the "master" label/taint to the above.
Primarily the change, in release 1.22, of how configuration objects
are maintained.
Also describe the new priority level.
Also move the sections on defaults and health check configuration to
follow the description of configuration objects.
The service account token one must have `serviceAccountName` specified
in order to be successfully validated.
The PV duplicate example can only refer to an existing volume.
I noticed a typo in a recent blog post, and a similar typo appears in
the comments for some examples. This PR corrects these typos.

The stateless application tutorial is littered with unsuitable terminology. This update switches the database technology to a database that has already updated their own terminology as well as removes the terminology from the tutorial itself.
The advanced logging tutorial followup is set to Draft as it will take a larger effort to convert that, and I'm not convinced its even in a working state right now.
A followup PR to the examples repo to be referenced here will be made.

The commit (a79db9d5de) made the sample
YAML for Ingress a standalone file, but it was placed into a NEW
`examples/ingress` directory. This PR moves it to
`examples/service/networking` subdirectory where all other Ingress
examples are located. Having a single file under a dedicated directory
seems not good.
Clarify that `REMOTE_PORT` is interpreted as identifying a _Service_ port when provided `TYPE` is `service`.
Also, highlight support for specifying a named port as `REMOTE_PORT`.
The #20553 changed the deprecated hello-node image to echoserver image. However, there is a reference to the old image later in the text. Point 5 implies that there will be a 'Hello World' message. This probably was true for the hello-node image but the echoserver does not print this (it echoes back the request with all of its params). This may be misleading, so change the text to a generic 'app's response'/'sample app'. Unused JS sources of the old image are removed.

DNS debugging documentation is using a busybox image as example.
This image has different known issues with the way it resolves
the DNS names in k8s, creating confusion with users that try to
follow the docs.
The e2e tests use a custom small image ~4.3MB for DNS testing
with all the necessary tools. Also, the fact that this image is
being used for the k8s e2e testing guarantees it's compatibility.

- Remove the tailing semicolon in 'xtrabackup_slave_info'.

Changes the key name to `SPECIAL_LEVEL` in the config map volume definition.
This is consistent with the rest of the example. Otherwise, this pod does not
start because there is no key with that name in the `special-config` config map.

In given manifest, podManagementPolicy is set as Parallel, but in later section of page, the console logs of "kubectl get pods -w -l app=zk" command displays ordered behavior, which is not the actual result in case of Parallel option.

Resolution :
Either change the value of podManagementPolicy option to OrderedReady or remove that option, so that StatefulSet will take it's default behavior.
It looks like `nginx -s quit` returns immediately rather than blocking until nginx has finished gracefully shutting down. As a result, just running `nginx -s quit` in the preStop hook won't work very well for high load and/or long running requests; nginx will get a TERM signal (and do a hard shutdown) immediately after `nginx -s quit` returns.
(I was getting connection errors while terminating pods, and adding a sleep-until-done to the preStop hook seemed to make them go away.)
