The `oom-score-adjust` option was added to prevent the daemon from being
OOM-killed before other processes. This option was mostly added as a
convenience, as running the daemon as a systemd unit was not yet common.
Having the daemon set its own limits is not best-practice, and something
better handled by the process-manager starting the daemon.
Docker v20.10 and newer no longer adjust the daemon's OOM score by default,
instead setting the OOM-score to the systemd unit (OOMScoreAdjust) that's
shipped with the packages.
Users currently depending on this feature are recommended to adjust the
daemon's OOM score using systemd or through other means, when starting
the daemon.

For moby/moby PR 45025 (Docker v24, API v1.43).
`docker run --annotation foo=bar` is similar to `podman run --annotation foo=bar`,
however, unlike Podman, Docker implementation also accepts an annotation with an empty value.
(`docker run --annotation foo`)

Set the client's API version that's used in the info, instead of requesting
it as part of printing.

Make this function only _print_ the info we have, and not read the username
from the credential-store.
This patch adds a Username field to the (local) `info` type, and sets it
when needed, so that prettyPrintServerInfo only has to format and print
the information, instead of calling out to the credential-store.

Starting with b4ca1c7368, docker login
no longer depends on info.IndexServerAddress to determine the default
registry.
The prettyPrintServerInfo() still depended on this information, which
could potentially show the wrong information.
This patch changes it to also depend on the same information as docker login
now does.

The IndexServerAddress field was as part of the initial Windows implementation
of the engine. For legal reasons, Microsoft Windows (and thus Docker images
based on Windows) were not allowed to be distributed through non-Microsoft
infrastructure. As a temporary solution, a dedicated "registry-win-tp3.docker.io"
registry was created to serve Windows images.
Currently, this field always shows "https://index.docker.io/v1/", which is
confusing, because that address is not used for the registry (only for
authentication and "v1" search).
docker info
...
Registry: https://index.docker.io/v1/
Starting with b4ca1c7368, this field is also
no longer used during authentication, and a3d56e7d06
removed the (deprecated) ElectAuthServer() which was previously used to
query it.
Given that there's currently no practical use for this information, and
it only adds "noise" (and confusion), this patch removes it from the default
output.
For now, the field is (still) available for those that want to use it;
docker info --format '{{.IndexServerAddress}}'
https://index.docker.io/v1/
But it won't be printed by default.

Deprecate this function in favor of the implementation in the API types,
considering that to be the canonical implementation.

This utility provides the same logic as was implemented here (and using it
aligns with the "docker pull" equivalent).
Also added a TODO to replace this function with the regular "docker pull"
code.

changes readInput() to trim whitespace. The existing code tried to be
conservative and only trimmed whitespace for username (not for password).
Passwords with leading/trailing whitespace would be _very_ unlikely, and
trimming whitespace is generally accepted.

ConfigureAuth used the readInput() utility to read the username and password.
However, this utility did not return errors it encountered, but instead did
an os.Exit(1). A result of this was that the terminal was not restored if
an error happened. When reading the password, the terminal is configured to
disable echo (i.e. characters are not printed), and failing to restore
the previous state means that the terminal is now "non-functional".
This patch:
- changes readInput() to return errors it encounters
- uses a defer() to restore terminal state

This function no longer uses the /info endpoint to resolve the registry
to use. The documentation for this function was still referring to
the (once used) special registry for Windows images, which is no longer
in use, so update the docs to reflect reality :)

This patch adds additional information to the Client section of the output.
We were already outputting versions of CLI Plugins, and the Server, but not
for the Client.
Adding this information can help with bug-reports where the reporter only
provided the `docker info` output, or (e.g.) only `docker --version`. The
platform name helps identify what kind of builds the user has installed
(e.g. docker's docker-ce packages have "Docker Engine - Community" set
for this), although we should consider including "packager" information
as a more formalized field for this information.
Before this patch:
$ docker info
Client:
Context: default
Debug Mode: false
Plugins:
buildx: Docker Buildx (Docker Inc.)
Version: v0.10.4
Path: /usr/libexec/docker/cli-plugins/docker-buildx

With this patch applied:
$ docker info
Client: Docker Engine - Community
Version: 24.0.0-dev
Context: default
Debug Mode: false

buildx: Docker Buildx (Docker Inc.)
Version: v0.10.4
