The `GetImageOpts` struct is used for options to be passed to the backend,
and are not used in client code. This struct currently is intended for internal
use only.
This patch moves the `GetImageOpts` struct to the backend package to prevent
it being imported in the client, and to make it more clear that this is part
of internal APIs, and not public-facing.

`VolumeOptions` now has a `Subpath` field which allows to specify a path
relative to the volume that should be mounted as a destination.
Symlinks are supported, but they cannot escape the base volume
directory.

The `ContainerCreateConfig` and `ContainerRmConfig` structs are used for
options to be passed to the backend, and are not used in client code.
Thess struct currently is intended for internal use only (for example, the
`AdjustCPUShares` is an internal implementation details to adjust the container's
config when older API versions are used).
Somewhat ironically, the signature of the Backend has a nicer UX than that
of the client's `ContainerCreate` signature (which expects all options to
be passed as separate arguments), so we may want to update that signature
to be closer to what the backend is using, but that can be left as a future
exercise.

Having a sandbox/container-wide MacAddress field makes little sense
since a container can be connected to multiple networks at the same
time. This field is an artefact of old times where a container could be
connected to a single network only.
As we now have a way to specify per-endpoint mac address, this field is
now deprecated.

Prior to this commit, only container.Config had a MacAddress field and
it's used only for the first network the container connects to. It's a
relic of old times where custom networks were not supported.

Fixes#18864, #20648, #33561, #40901.
[This GH comment][1] makes clear network name uniqueness has never been
enforced due to the eventually consistent nature of Classic Swarm
datastores:
> there is no guaranteed way to check for duplicates across a cluster of
> docker hosts.
And this is further confirmed by other comments made by @mrjana in that
same issue, eg. [this one][2]:
> we want to adopt a schema which can pave the way in the future for a
> completely decentralized cluster of docker hosts (if scalability is
> needed).
This decentralized model is what Classic Swarm was trying to be. It's
been superseded since then by Docker Swarm, which has a centralized
control plane.
To circumvent this drawback, the `NetworkCreate` endpoint accepts a
`CheckDuplicate` flag. However it's not perfectly reliable as it won't
catch concurrent requests.
Due to this design decision, API clients like Compose have to implement
workarounds to make sure names are really unique (eg.
docker/compose#9585). And the daemon itself has seen a string of issues
due to that decision, including some that aren't fixed to this day (for
instance moby/moby#40901):
> The problem is, that if you specify a network for a container using
> the ID, it will add that network to the container but it will then
> change it to reference the network by using the name.
To summarize, this "feature" is broken, has no practical use and is a
source of pain for Docker users and API consumers. So let's just remove
it for _all_ API versions.

PR 4f47013feb added a validation step to `NetworkCreate` to ensure
no IPv6 subnet could be set on a network if its `EnableIPv6` parameter
is false.
Before that, the daemon was accepting such request but was doing nothing
with the IPv6 subnet.
This validation step is now deleted, and we automatically set
`EnableIPv6` if an IPv6 subnet was specified.

Define consts for the Actions we use for events, instead of "ad-hoc" strings.
Having these consts makes it easier to find where specific events are triggered,
makes the events less error-prone, and allows documenting each Action (if needed).

Make the error message slightly clearer on "what" part is not valid,
and provide suggestions on what are acceptable values.
Before this change:
docker create --restart=always:3 busybox
Error response from daemon: invalid restart policy: maximum retry count cannot be used with restart policy 'always'
docker create --restart=always:-1 busybox
Error response from daemon: invalid restart policy: maximum retry count cannot be used with restart policy 'always'
docker create --restart=unknown busybox
Error response from daemon: invalid restart policy 'unknown'
After this change:
docker create --restart=always:3 busybox
Error response from daemon: invalid restart policy: maximum retry count can only be used with 'on-failure'
docker create --restart=always:-1 busybox
Error response from daemon: invalid restart policy: maximum retry count can only be used with 'on-failure' and cannot be negative
docker create --restart=unknown busybox
Error response from daemon: invalid restart policy: unknown policy 'unknown'; use one of 'no', 'always', 'on-failure', or 'unless-stopped'

Currently, IPAM config is never validated by the API. Some checks
are done by the CLI, but they're not exhaustive. And some of these
misconfigurations might be caught early by libnetwork (ie. when the
network is created), and others only surface when connecting a container
to a misconfigured network. In both cases, the API would return a 500.
Although the `NetworkCreate` endpoint might already return warnings,
these are never displayed by the CLI. As such, it was decided during a
maintainer's call to return validation errors _for all API versions_.

The is-automated field is being deprecated by Docker Hub's search API,
and will always be set to "false" in future.
This patch deprecates the field and related filter for the Engine's API.
In future, the `is-automated` filter will no longer yield any results
when searching for `is-automated=true`, and will be ignored when
searching for `is-automated=false`.
Given that this field is deprecated by an external API, the deprecation
will not be versioned, and will apply to any API version.
