Finishes off the work to change references to cluster volumes in the API
from using "csi" as the magic word to "cluster". This reflects that the
volumes are "cluster volumes", not "csi volumes".
Notably, there is no change to the plugin definitions being "csinode"
and "csicontroller". This terminology is appropriate with regards to
plugins because it accurates reflects what the plugin is.

when executing commands that output some kind of text user interface
which is bounded by the console dimensions.

Starting with the 22.06 release, buildx is the default client for
docker build, which uses BuildKit as builder.
This patch changes the default builder version as advertised by
the daemon to "2" (BuildKit), so that pre-22.06 CLIs with BuildKit
support (but no buildx installed) also default to using BuildKit
when interacting with a 22.06 (or up) daemon.

Using the swagger.yaml to generate api models will create incompatible field types. Some inconsistencies had already been mentioned at #39131. I've added more fixes from real life experience, some only occurring on Windows.

On Linux the daemon was not respecting the HostConfig.ConsoleSize
property and relied on cli initializing the tty size after the container
was created. This caused a delay between container creation and
the tty actually being resized.
This is also a small change to the api description, because
HostConfig.ConsoleSize is no longer Windows-only.

Containers can have a default stop-signal (`--stop-signal` / `STOPSIGNAL`) and
timeout (`--stop-timeout`). It is currently not possible to update either of
these after the container is created (`docker update` does not allow updating
them), and while either of these can be overridden through some commands, we
currently do not have a command that can override *both*:
command | stop-signal | stop-timeout | notes
----------------|-------------|--------------|----------------------------
docker kill | yes | DNA | only sends a single signal
docker restart | no | yes |
docker stop | no | yes |
As a result, if a user wants to stop a container with a custom signal and
timeout, the only option is to do this manually:
docker kill -s <custom signal> mycontainer
# wait <desired timeout>
# press ^C to cancel the graceful stop
# forcibly kill the container
docker kill mycontainer
This patch adds a new `signal` query parameter to the container "stop" and
"restart" endpoints. This parameter can be added as a new flag on the CLI,
which would allow stopping and restarting with a custom timeout and signal,
for example:
docker stop --signal=SIGWINCH --time=120 mycontainer
docker restart --signal=SIGWINCH --time=120 mycontainer

ContainerConfig is used in multiple locations (for example, both for
Image.Config and Image.ContainerConfig). Unfortunately, swagger does
not allow documenting individual uses if a type is used; for this type,
the content is _optional_ when used as Image.ContainerConfig (which is
set by the classic builder, which does a "commit" of a container, but
not used when building an image with BuildKit).
This patch attempts to address this confusion by documenting that
"it may be empty (or fields not propagated) if it's used for the
Image.ContainerConfig field".
Perhaps alternatives are possible (aliasing the type?) but we can
look at those in a follow-up.

This adds an additional "Swarm" header to the _ping endpoint response,
which allows a client to detect if Swarm is enabled on the daemon, without
having to call additional endpoints.
This change is not versioned in the API, and will be returned irregardless
of the API version that is used. Clients should fall back to using other
endpoints to get this information if the header is not present.

- Omit `KernelMemory` and `KernelMemoryTCP` fields in `/info` response if they're
not supported, or when using API v1.42 or up.
- Re-enable detection of `KernelMemory` (as it's still needed for older API versions)
- Remove warning about kernel memory TCP in daemon logs (a warning is still returned
by the `/info` endpoint, but we can consider removing that).
- Prevent incorrect "Minimum kernel memory limit allowed" error if the value was
reset because it's not supported by the host.

This field was used when Windows did not yet support regular images, and required
the base-image to pre-exist on the Windows machine (as those layers were not yet
allowed to be distributed).
Commit f342b27145 (docker 1.13.0, API v1.25) removed
usage of the field. The field was not documented in the API, but because it was not
removed from the Golang structs in the API, ended up in the API documentation when
we switched to using Swagger instead of plain MarkDown for the API docs.

- rename definition in swagger from `Image` to `ImageInspect` to match the go type
- improve (or add) documentation for various fields
- move example values in-line in the "definitions" section
- remove the `required` fields from `ImageInspect`, as the type is only used as
response type (not to make requests).

This patch updates the swagger, and:

- updates the description to mention both "omitted" and "empty" values (although

Commit 0380fbff37 added the ability to pass a
--platform flag on `docker import` when importing an archive. The intent
of that commit was to allow importing a Linux rootfs on a Windows daemon
(as part of the experimental LCOW feature).
A later commit (337ba71fc1) changed some
of this code to take both OS and Architecture into account (for `docker build`
and `docker pull`), but did not yet update the `docker image import`.
This patch updates the import endpoitn to allow passing both OS and
Architecture. Note that currently only matching OSes are accepted,
and an error will be produced when (e.g.) specifying `linux` on Windows
and vice-versa.

While the field in the Go struct is named `NanoCPUs`, it has a JSON label to
use `NanoCpus`, which was added in the original pull request (not clear what
the reason was); 846baf1fd3
Some notes:
- Golang processes field names case-insensitive, so when *using* the API,
both cases should work, but when inspecting a container, the field is
returned as `NanoCpus`.
- This only affects Containers.Resources. The `Limits` and `Reservation`
for SwarmKit services and SwarmKit "nodes" do not override the name
for JSON, so have the canonical (`NanoCPUs`) casing.

Current description of the "v" option doesn't explain what happens to
the volumes that are still in use by other containers. Turns out that
the only volumes that are removed are unnamed ones[1].
Perhaps a good way of clarifying this behavior would be adapting the
description from "docker rm --help".
As for the docs/api/v1.*.yaml changes — they seem to be applicable,
since the origin of this behavior dates way back to the 2016 or v1.11[2].

This patch adds a new "prune" event type to indicate that pruning of a resource
type completed.
This event-type can be used on systems that want to perform actions after
resources have been cleaned up. For example, Docker Desktop performs an fstrim
after resources are deleted (https://github.com/linuxkit/linuxkit/tree/v0.7/pkg/trim-after-delete).
While the current (remove, destroy) events can provide information on _most_
resources, there is currently no event triggered after the BuildKit build-cache
is cleaned.
Prune events have a `reclaimed` attribute, indicating the amount of space that
was reclaimed (in bytes). The attribute can be used, for example, to use as a
threshold for performing fstrim actions. Reclaimed space for `network` events
will always be 0, but the field is added to be consistent with prune events for
other resources.
To test this patch:
Create some resources:
for i in foo bar baz; do \
docker network create network_$i \
&& docker volume create volume_$i \
&& docker run -d --name container_$i -v volume_$i:/volume busybox sh -c 'truncate -s 5M somefile; truncate -s 5M /volume/file' \
&& docker tag busybox:latest image_$i; \
done;
docker pull alpine
docker pull nginx:alpine
echo -e "FROM busybox\nRUN truncate -s 50M bigfile" | DOCKER_BUILDKIT=1 docker build -
Start listening for "prune" events in another shell:
docker events --filter event=prune
Prune containers, networks, volumes, and build-cache:
docker system prune -af --volumes
See the events that are returned:
docker events --filter event=prune

After dicussing with maintainers, it was decided putting the burden of
providing the full cap list on the client is not a good design.
Instead we decided to follow along with the container API and use cap
add/drop.
This brings in the changes already merged into swarmkit.

The initial implementation followed the Swarm API, where
PidsLimit is located in ContainerSpec. This is not the
desired place for this property, so moving the field to
TaskTemplate.Resources in our API.
A similar change should be made in the SwarmKit API (likely
keeping the old field for backward compatibility, because
it was merged some releases back)

This introduces A new type (`Limit`), which allows Limits
and "Reservations" to have different options, as it's not
possible to make "Reservations" for some kind of limits.
The `GenericResources` have been removed from the new type;
the API did not handle specifying `GenericResources` as a
_Limit_ (only as _Reservations_), and this field would
therefore always be empty (omitted) in the `Limits` case.
