The `--kernel-memory` flag was still included to allow it to be used with
old API versions, but it's no longer supported by the kernel, and no longer
handled by OCI runtimes, so deprecating the flags.
With this patch, a deprecation warning is now produced when trying to use
the option;
docker run --kernel-memory 123b busybox
Flag --kernel-memory has been deprecated, this option is deprecated in the kernel and no longer supported
docker container create --kernel-memory 123b busybox
Flag --kernel-memory has been deprecated, and no longer supported by the kernel

Note that cobra does not _fail_ the command when using deprecated options;
we could make this a hard failure instead, but may not be worth the effort.

This only impacts the JSON marshaled output; the "regular" output
of `docker info` already ignores these fields.
Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
Go does not by default marshal `error` type fields to JSON. The manager
package therefore implemented a `pluginError` type that implements
[encoding.TextMarshaler]. However, the field was marked as a regular
`error`, which made it brittle; assining any other type of error would
result in the error being discarded in the marshaled JSON (as used in
`docker info` output), resulting in the error being marshaled as `{}`.
This patch adds a custom `MarshalJSON()` on the `Plugin` type itself
so that any error is rendered. It checks if the error used already
implements [encoding.TextMarshaler], otherwise wraps the error in
a `pluginError`.

This is a follow-up to 55e404e7a8, which
removed some warnings related to these fields.
These fields in the /info response were used to warn users if netfiltering
was not enabled on the host when the daemon started. Starting with
[moby@db25b0d], detecting whether netfiltering is enabled now
[happens when needed][1], making the state that's detected at startup
irrelevant.
These fields will therefore be deprecated in future, but we can start
removing their use in tests.

This error didn't do a great job at formatting. If a StatusError was
produced without a Status message, it would print a very non-informative
error, with information missing.
Let's update the output:
- If a status-message is provided; print just that (after all the
status code is something that can be found from the shell, e.g.
through `echo $?` in Bash).
- If no status-message is provided: print a message more similar to
Go's `exec.ExecError`, which uses `os.rocessState.String()` (see [1]).
Before this patch, an error without custom status would print:
Status: , Code: 2
After this patch:
exit status 2
In situations where a custom error-message is provided, the error-message
is print as-is, whereas before this patch, the message got combined with
the `Status:` and `Code:`, which resulted in some odd output.
Before this patch:
docker volume --no-such-flag
Status: unknown flag: --no-such-flag
See 'docker volume --help'.
Usage: docker volume COMMAND

Commands:
create Create a volume
inspect Display detailed information on one or more volumes

Docker Engine 18.09 (API v1.39) introduced a Warnings field in the into response.
This enhancement was not gated by API version (see [moby/moby@a3d4238]), and
will be returned by Docker Engine 18.09 and up, regardless of the API version
chosen.
Likewise, the client-side code was written to prefer warnings returned by
the daemon, but to fall back on client-side detection of missing features
based on information in the Info response (see [docker/cli@3c27ce2]).
Thse warnings are purely informational, and given that Docker Engine versions
before 18.09 have reached EOL 6 Years ago, and any current version of the
Engine now returns the Warnings, it should be safe to remove the client-side
fall back logic.
This patch removes the client-side fall back code for warnings that was
added in 3c27ce21c9.

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.

Not a fan of aliases, but unfortunately they're sometimes needed. We import both
docker/docker/registry and docker/registry and api/types/registry, so I looked
for which one to continue using an alias, and this was the one "least" used,
and which already used this alias everywhere, except for two places.

The docker info output contains both "local" and "remote" (daemon-side) information.
The API endpoint to collect daemon information (`/info`) is known to be "heavy",
and (depending on what information is needed) not needed.
This patch checks if the template (`--format`) used requires information from the
daemon, and if not, omits making an API request.
This will improve performance if (for example), the current "context" is requested
from `docker info` or if only plugin information is requested.

Fairly straight forward. It became necessary to wrap `Plugin.Err` with a type
