Diffing a container yielded some extra changes that come from the
files/directories that we mount inside the container (/etc/resolv.conf
for example). To avoid that we create an intermediate snapshot that has
these files, with this we can now diff the container fs with its parent
and only get the differences that were made inside the container.

The API endpoint `/containers/create` accepts several EndpointsConfig
since v1.22 but the daemon would error out in such case. This check is
moved from the daemon to the api and is now applied only for API < 1.44,
effectively allowing the daemon to create containers connected to
several networks.

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been superseded since then by Docker Swarm, which has a centralized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.

container.Run() should be a synchronous operation in normal circumstances;
the container is created and started, so polling after that for the
container to be in the "running" state should not be needed.
This should also prevent issues when a container (for whatever reason)
exited immediately after starting; in that case we would continue
polling for it to be running (which likely would never happen).
Let's skip the polling; if the container is not in the expected state
(i.e. exited), tests should fail as well.

The daemon would pass an EndpointCreateOption to set the interface MAC
address if the network name and the provided network mode were matching.
Obviously, if the network mode is a network ID, it won't work. To make
things worse, the network mode is never normalized if it's a partial ID.
To fix that: 1. the condition under what the container's mac-address is
applied is updated to also match the full ID; 2. the network mode is
normalized to a full ID when it's only a partial one.

container.Run should be an synchronous operation; the container should
be running after the request was made (or produce an error). Simplify
these tests, and remove the redundant polling.
These were added as part of 8f800c9415,
but no such polls were in place before the refactor, and there's no
mention of these during review of the PR, so I assume these were just
added either as a "precaution", or a result of "copy/paste" from another
test.

This test was failing frequently on Windows, where the test was waiting
for the container to exit before continuing;
=== FAIL: github.com/docker/docker/integration/container TestResizeWhenContainerNotStarted (18.69s)
resize_test.go:58: timeout hit after 10s: waiting for container to be one of (exited), currently running
It looks like this test is merely validating that a container in any non-
running state should produce an error, so there's no need to run a container
(waiting for it to stop), and just "creating" a container (which would be
in `created` state) should work for this purpose.
Looking at 8f800c9415, I see `createSimpleContainer`
and `runSimpleContainer` utilities were added, so I'm even wondering if the
original intent was to use `createSimpleContainer` for this test.
While updating, also check if we get the expected error-type, instead of
only checking for the error-message.

This uses otel standard environment variables to configure tracing in
the daemon.
It also adds support for propagating trace contexts in the client and

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).

`Daemon.getPidContainer()` was wrapping the error-message with a message
("cannot join PID of a non running container") that did not reflect the
actual reason for the error; `Daemon.GetContainer()` could either return
an invalid parameter (invalid / empty identifier), or a "not found" error
if the specified container-ID could not be found.
In the latter case, we don't want to return a "not found" error through
the API, as this would indicate that the container we're _starting_ was
not found (which is not the case), so we need to convert the error into
an `errdefs.ErrInvalidParameter` (the container-ID specified for the PID
namespace is invalid if the container doesn't exist).
This logic is similar to what we do for IPC namespaces. which received
a similar fix in c3d7a0c603.
This patch updates the error-types, and moves them into the getIpcContainer
and getPidContainer container functions, both of which should return
an "invalid parameter" if the container was not found.
It's worth noting that, while `WithNamespaces()` may return an "invalid
parameter" error, the `start` endpoint itself may _not_ be. as outlined
in commit bf1fb97575, starting a container
that has an invalid configuration should be considered an internal server
error, and is not an invalid _request_. However, for uses other than
container "start", `WithNamespaces()` should return the correct error
to allow code to handle it accordingly.

This utility was only used for a single test, and it was very limited
in functionality as it only allowed for a certain error-string to be
matched.
Let's change it into a more generic function; a helper that allows a
container to be created from a `TestContainerConfig` (which can be
constructed using `NewTestConfig`) and that returns the response from
client.ContainerCreate(), so that any result from that can be tested,
leaving it up to the test to check the results.
