Update docs/command output for volume pruning
In previous versions of the Docker API, `system prune --volumes` and `volume prune`
would remove all dangling volumes. With API v1.42, this was changed so that only
anonymous volumes would be removed unless the all filter was specified.

Some of the docs were updated in #4218, however, there were a couple of places
left that didn't make the anonymous vs named volumes distinction clear.

This replaces #4079, which was bitrotted by #4218. See also #4028.

Closes #4079.

now does.

docker info: don't print "registry" (IndexServerAddress)
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.

docker info: include Client Version and "platform name"
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

format (GoDoc) comments with Go 1.19 to prepare for go updates
Older versions of Go do not format these comments, so we can already
reformat them ahead of time to prevent gofmt linting failing once
we update to Go 1.19 or up.

Result of:

    gofmt -s -w $(find . -type f -name '*.go' | grep -v "/vendor/")

With some manual adjusting.

Sebastiaan van Stijn 80b1285fec cli: use custom annotation for aliases
Cobra allows for aliases to be defined for a command, but only allows these
to be defined at the same level (for example, `docker image ls` as alias for
`docker image list`). Our CLI has some commands that are available both as a
top-level shorthand as well as `docker <object> <verb>` subcommands. For example,
`docker ps` is a shorthand for `docker container ps` / `docker container ls`.

This patch introduces a custom "aliases" annotation that can be used to print
all available aliases for a command. While this requires these aliases to be
defined manually, in practice the list of aliases rarely changes, so maintenance
should be minimal.

As a convention, we could consider the first command in this list to be the
canonical command, so that we can use this information to add redirects in
our documentation in future.

Before this patch:

    docker images --help

    Usage:  docker images [OPTIONS] [REPOSITORY[:TAG]]

    List images

    Options:
      -a, --all             Show all images (default hides intermediate images)
      ...

With this patch:

    docker images --help

    Usage:  docker images [OPTIONS] [REPOSITORY[:TAG]]

    List images

    Aliases:
      docker image ls, docker image list, docker images

    Options:
      -a, --all             Show all images (default hides intermediate images)

info: improve handling of empty Info
Before this change, the function could print an error in some cases, for example;

```bash
docker -H tcp://127.0.0.1:2375 info --format '{{.LoggingDriver}}'

template: :1:2: executing "" at <.LoggingDriver>: reflect: indirection through nil pointer to embedded struct field Info
```

With this patch applied, the error is handled gracefully, and when failing to
connect with the daemon, the error is logged;

```bash
docker -H tcp://127.0.0.1:2375 info --format '{{.LoggingDriver}}'
Cannot connect to the Docker daemon at tcp://127.0.0.1:2375. Is the docker daemon running?

docker -H tcp://127.0.0.1:2375 info --format '{{json .}}'
Cannot connect to the Docker daemon at tcp://127.0.0.1:2375. Is the docker daemon running?
{"ID":"","Containers":0,"..."}}
```

Note that the connection error is also included in the JSON `ServerErrors` field,
so that the information does not get lost, even if STDERR would be redirected;

```bash
docker -H tcp://127.0.0.1:2375 info --format '{{json .ServerErrors}}' 2> /dev/null
["Cannot connect to the Docker daemon at tcp://127.0.0.1:2375. Is the docker daemon running?"]
```
