This change is to update the documentation for reserved-memory flag.
Now, for specifying memory reservations across multiple NUMA nodes,
semicolon needs to be used as separator.

The command "kubeadm kubeconfig user" is missing
some examples and more details on why it is needed.
- Add a new section "Generating kubeconfig files
for additional users" under the kubeadm-certs page.
- Link to this section from the kubeadm-kubeconfig reference page.
- Link to this section from the create-cluster-kubeadm page.
Sysbox is an open-source container runtime (similar to "runc") that supports
running VM-workloads such as Docker and Kubernetes inside unprivileged
containers or pods.
Sysbox containers always use the Linux user-namespace for isolation, plus
specially crafted proc and sys filesystems, some syscall interception,
filesystem ID-mapping, and more.
It's possible to run Kubernetes, K3s, K0s, inside containers or pods deployed
with Sysbox. This commit aims to make the Kubernetes community aware of this
option.

Touch the following files:
- Implementation details: remove docker specifics, which is changing
in 1.24
- Create cluster: small language cleanup, remove note about 1.24
- Install kubeadm: Include two up-to-date tables for Linux / Windows
with known endpoints. Include cri-dockerd.
- Kubelet integration: (side cleanup) use "container runtime" instead of
"CRI runtime" (which is incorrect). Mention that only updating
"--container-runtime-endpoint=.." is required if the user wishes
to override the CR on a certain host. Dockershim->CR-foo migration
guides would make the "--container-runtime=remote" flag explicit
and we want to remove it at some point.
- Troubleshooting kubeadm: Remove some instances of Docker troubleshooting
that imply docker as default CR, or talk about old Docker versions.
Be more generic about container runtimes.
- Adding Windows nodes: move the containerd tab before the Docker
tab, as containerd is now the default. Remove note about being explicit
about --cri-socket. Add note that crictl is required for both
Docker and containerd. Add note that cri-dockerd is required if
the user wants to use Docker EE on Windows.
The current entry under additional information about drain can
be confusing and users might jump into draining the nodes before
the upgrade steps (as a pre-req), following the
instructions in the external link. This is not accurate.
Adjust the entry text to explain that drain is a step as part of
the upgrade process and this additional information entry just
mentions why it is needed.
This commit reformats the memory manager page:
- convert the page from DOS to UNIX format;
- wrap long lines where appropriate for ease of change tracking;
- remove useless trailing spaces and empty lines.
This commit contains **NO** changes to the text itself.
This PR fixes the memory manager page by:
- removing links to non-existent sections;
- fixing links with bad anchors;
- fixing incorrect language tag for code snippets
Revise tasks within “Manage Memory, CPU, and API Resources”:
- reword to avoid implying that API clients can create a container
(you can, but its done by creating a Pod)
- call a manifest a manifest
- use tooltips where relevant
- link to new API reference not the old one
- other improvements
* Update kubeadm-upgrade.md
`apt-mark hold` is still required when `apt-get` is used with `--allow-change-held-packages`.
`--allow-change-held-packages` unholds the package but it doesn't pin the new version.
* Add missing changes
* Update kubeadm-upgrade.md
Remove apt >1.1 examples.
* Update docs to clarify the dns configmap format.
* Update content/en/docs/tasks/administer-cluster/nodelocaldns.md

* kubelet-in-userns.md: fix unexpected config paths
Referring to `/etc/containerd/config.toml` makes sense only when the user has
read/write permissions to `/etc/containerd/config.toml` in the current mount
namespace, which is not always assumed in the context of this documentation.
The same applies to `/etc/crio/crio.conf`, too.
Partially revert PR 30020.

* kubelet-in-userns.md: add back the link to example port forwarder implementation
Add back the link to `k3s/pkg/rootlessports/controller.go` removed in PR 30020.
As stated in `{{ <note> }}`, the corresponding section is written for developers
of Kubernetes distros, not for end users.
So we should retain the implementation details here.
Partially revert PR 30020.
