The OOMKilled flag on a container's state has historically behaved
rather unintuitively: it is updated on container exit to reflect whether
or not any process within the container has been OOM-killed during the
preceding run of the container. The OOMKilled flag would be set to true
when the container exits if any process within the container---including
execs---was OOM-killed at any time while the container was running,
whether or not the OOM-kill was the cause of the container exiting. The
flag is "sticky," persisting through the next start of the container;
only being cleared once the container exits without any processes having
been OOM-killed that run.
Alter the behavior of the OOMKilled flag such that it signals whether
any process in the container had been OOM-killed since the most recent
start of the container. Set the flag immediately upon any process being
OOM-killed, and clear it when the container transitions to the "running"
state.
There is an ulterior motive for this change. It reduces the amount of
state the libcontainerd client needs to keep track of and clean up on
container exit. It's one less place the client could leak memory if a
container was to be deleted without going through libcontainerd.

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.

Now client have the possibility to set the console size of the executed
process immediately at the creation. This makes a difference for example
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.
Closes#39131

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.

This fixes the "deprecated" comment to have the correct format to be picked
up by editors, and adds `omitempty` labels for KernelMemory and KernelMemoryTCP.

- 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).
