The strslice.StrSlice type is a string-slice with a custom JSON Unmarshal
function to provide backward-compatibility with older API requests from
before docker 1.7 (see [moby@17d6f00] and [moby@ea4a067]), which used a
string instead of an array of strings for some fields (Cmd, Entrypoint).
We no longer support those API versions, and we no longer support pulling
v1 images that may contain such a config, so we can remove these tests that
validate the behavior as they're invalid API requests.
This;
- removes DockerAPISuite.TestPostContainerAPICreateWithStringOrSliceEntrypoint
- removes DockerAPISuite.TestPostContainersCreateWithStringOrSliceCmd
- removes DockerAPISuite.TestPostContainersCreateWithStringOrSliceCapAddDrop
- updates DockerAPISuite.TestContainerAPIPostCreateNull, which used an invalid example

Because:
- it's the last thing outside 'daemon/' that uses libnetwork's
resolvconf package
- there's better coverage of the host resolv.conf transformations
in the resolvconf package's unit tests
- there are integration tests that don't modify the test host's
resolv.conf file in 'integration/networking/resolvconf_test.go'

commit 4dc961d0e9 removed deprecated
fields from the image inspect response for API v1.50 and up. As
part of that change, it changed the type used for the Config field
to use the docker image spect structs, which embeds the OCI image
spec structs.
While the OCI image spect struct contains the same fields as we
used before, those fields also have "omitempty" set, which means
they are now omitted when empty.
We should probably consider deprecating that behavior in the API,
and call out that these fields are omitted if not set, but in the
meantime, we can add them back with their default (zero) value.

These comments were added to enforce using the correct import path for
our packages ("github.com/docker/docker", not "github.com/moby/moby").
However, when working in go module mode (not GOPATH / vendor), they have
no effect, so their impact is limited.
Remove these imports in preparation of migrating our code to become an
actual go module.

commit af0cdc36c7 marked these fields as
deprecated and to be removed in API v1.47 (which was targeted for v28.0).
We shipped v1.47 with the v27.2 release, but did not yet remove the erroneous
fields, so the version to deprecate was updated to v1.48 through
3df03d8e66
This patch removes fields that are not part of the image by replacing the
type with the Config struct from the docker image-spec.

gotest.tools v3.0.1 and up support Go's native test.Cleanup(), which
means that manually calling the cleanup functions in a defer is no
longer needed.
Some of these could probably be replaced by Go's native `t.TempDir()`,
but keeping that for a follow-up exercise.

It's possible to remove a legacy link from running containers.
When that happens, the Sandbox's Endpoints are removed and
re-added.
Since commit 65120d5 ("Create bridge veth in container netns")
the veth device has been created in the container's netns. When
that happens, a flag is set on the Endpoint to note that it
does not need to be moved into the netns.
But, during the Leave/Join (Sandbox.Refresh) the veth is moved
out of the netns. So, clear the flag during the Leave, to note
that it needs to be moved back in during the Join.

Docker 25.0 (08e4e88482) deprecated API versions
older than v1.24, and support was removed in Docker 26.0.
As part of this deprecation, support for plain-text errors was also removed
in commit ffd877f948.
So while we no longer support API versions older 1.24 [api.MinSupportedAPIVersion],
a client may try to connect using an older version and expect a plain-text error
instead of a JSON error. This would result in an "API version too old" error
formatted in JSON being printed as-is.
DOCKER_API_VERSION=v1.10 docker info --format '{{.ID}}'
Error response from daemon: {"message":"client version 1.10 is too old. Minimum supported API version is 1.24, please upgrade your client to a newer version"}
curl --unix-socket /var/run/docker.sock http://localhost/v1.10/info
{"message":"client version 1.10 is too old. Minimum supported API version is 1.24, please upgrade your client to a newer version"}
Note that this was only a problem for old API versions; unsupported API versions
that were higher than the maximum version were already handled as JSON;
DOCKER_API_VERSION=v1.99 docker info --format '{{.ID}}'
Error response from daemon: client version 1.99 is too new. Maximum supported API version is 1.48
curl --unix-socket /var/run/docker.sock http://localhost/v1.99/info
{"message":"client version 1.99 is too new. Maximum supported API version is 1.48"}
Let's be nice, and return errors in plain-text to provide a more readable error
to help the user understand the API version they're using is no longer supported.
With this patch applied:
DOCKER_API_VERSION=v1.10 docker info --format '{{.ID}}'
Error response from daemon: client version 1.10 is too old. Minimum supported API version is 1.24, please upgrade your client to a newer version
curl --unix-socket /var/run/docker.sock http://localhost/v1.10/info

Split the `ErrConflictHostNetwork` error into two distinct errors:
1. `ErrConflictConnectToHostNetwork` when attempting to change the
network mode of a running container from a different mode to `host`
2. `ErrConflictDisconnectFromHostNetwork` when the network mode of a
running container is `host` and attempting to disconnect from `host`
This commit clarifies error messaging by differentiating between the two
errors, making it clearer which operation failed and how to fix it.
