This field was added in f0e5b3d7d8 to
account for older versions of the engine (Docker EE LTS versions), which
did not yet provide the OSType field in Docker info, and had to be manually
set using the TEST_OSTYPE env-var.
This patch removes the field in favor of the equivalent in DaemonInfo. It's
more verbose, but also less ambiguous what information we're using (i.e.,
the platform the daemon is running on, not the local platform).

Before 4bafaa00aa, if the daemon was
killed while a container was running and the container shim is killed
before the daemon is restarted, such as if the host system is
hard-rebooted, the daemon would restore the container to the stopped
state and set the exit code to 255. The aforementioned commit introduced
a regression where the container's exit code would instead be set to 0.
Fix the regression so that the exit code is once against set to 255 on
restore.

Contrary to popular belief, the OCI Runtime specification does not
specify the command-line API for runtimes. Looking at containerd's
architecture from the lens of the OCI Runtime spec, the _shim_ is the
OCI Runtime and runC is "just" an implementation detail of the
io.containerd.runc.v2 runtime. When one configures a non-default runtime
in Docker, what they're really doing is instructing Docker to create
containers using the io.containerd.runc.v2 runtime with a configuration
option telling the runtime that the runC binary is at some non-default
path. Consequently, only OCI runtimes which are compatible with the
io.containerd.runc.v2 shim, such as crun, can be used in this manner.
Other OCI runtimes, including kata-containers v2, come with their own
containerd shim and are not compatible with io.containerd.runc.v2.
As Docker has not historically provided a way to select a non-default
runtime which requires its own shim, runtimes such as kata-containers v2
could not be used with Docker.
Allow other containerd shims to be used with Docker; no daemon
configuration required. If the daemon is instructed to create a
container with a runtime name which does not match any of the configured
or stock runtimes, it passes the name along to containerd verbatim. A
user can start a container with the kata-containers runtime, for
example, simply by calling
docker run --runtime io.containerd.kata.v2
Runtime names which containerd would interpret as a path to an arbitrary
binary are disallowed. While handy for development and testing it is not
strictly necessary and would allow anyone with Engine API access to
trivially execute any binary on the host as root, so we have decided it
would be safest for our users if it was not allowed.
It is not yet possible to set an alternative containerd shim as the
default runtime; it can only be configured per-container.

testutil/daemon uses a generic unix implementation that assumes that
the host OS supports cgroups & network namespaces, which is not the
case for FreeBSD.
This change adds a FreeBSD-specific implementation for
`testutil/daemon`, namely for `cleanupNetworkNamespace` and
`CgroupNamespace` functions.

Update the frozen images to also be based on Debian bullseye. Using the "slim"
variant (which looks to have all we're currently using), and remove the
buildpack-dep frozen image.
The buildpack-dep image is quite large, and it looks like we only use it to
compile some C binaries, which should work fine on a regular debian image;
docker build -t debian:bullseye-slim-gcc -<<EOF
FROM debian:bullseye-slim
RUN apt-get update && apt-get install -y gcc libc6-dev --no-install-recommends
EOF
docker image ls

This option was originally added in d05aa418b0,
and moved in 8b15839ee8 (after which it temporarily
went to the docker/engine-api repository, and was brought back in this repository
in 91e197d614).
However, it looks like this field was never used; the API always returns the standard
information, and the "--quiet" option for `docker ps` is implemented on the CLI
side, which uses different formatting when setting this option;
