setupTest should be called before Parallel as it modifies the test
environment which might produce:
```

Layer size is the sum of the individual files count, not the tar
archive. Use the total bytes read returned by `io.Copy` to populate the
`Size` field.
Also set the digest to the actual digest of the tar archive.

The new OCI-compatible archive export relies on the Descriptors returned
by the layer (`distribution.Describable` interface implementation).
The issue with that is that the `roLayer` and the `referencedCacheLayer`
types don't implement this interface. Implementing that interface for
them based on their `descriptor` doesn't work though, because that
descriptor is empty.
To workaround this issue, just create a new descriptor if the one
provided by the layer is empty.

The graphdriver implementation sets the ModTime of all image content to
match the `Created` time from the image config, whereas the containerd's
archive export code just leaves it empty (zero).
Adjust the test in the case where containerd integration is enabled to
check if config file ModTime is equal to zero (UNIX epoch) instead.
This behaviour is not a part of the Docker Image Specification and the
intention behind introducing it was to make the `docker save` produce
the same archive regardless of the time it was performed.
It would also be a bit problematic with the OCI archive layout which can
contain multiple images referencing the same content.

This delete was originally added in b37fdc5dd1
and migrated from `deleteImages(repoName)` in commit 1e55ace875,
however, deleting `foobar-save-multi-images-test` (`foobar-save-multi-images-test:latest`)
always resulted in an error;
Error response from daemon: No such image: foobar-save-multi-images-test:latest
This patch removes the redundant image delete.

Shutting down containers on Windows can take a long time (with hyper-v),
causing this test to be flaky; seen failing on windows 2022;
=== FAIL: github.com/docker/docker/integration/image TestSaveRepoWithMultipleImages (23.16s)
save_test.go:104: timeout waiting for container to exit
Looking at the test, we run a container only to commit it, and the test
does not make changes to the container's filesystem; it only runs a container
with a custom command (`true`).
Instead of running the container, we can _create_ a container and commit it;
this simplifies the tests, and prevents having to wait for the container to
exit (before committing).
To verify:
make BIND_DIR=. DOCKER_GRAPHDRIVER=vfs TEST_FILTER=TestSaveRepoWithMultipleImages test-integration
INFO: Testing against a local daemon
=== RUN TestSaveRepoWithMultipleImages
--- PASS: TestSaveRepoWithMultipleImages (1.20s)

Implement a behavior from the graphdriver's export where `docker save
something` (untagged reference) would export all images matching the
specified repository.

Integration tests will now configure clients to propagate traces as well
as create spans for all tests.
Some extra changes were needed (or desired for trace propagation) in the
test helpers to pass through tracing spans via context.

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).

This makes the output of `docker save` fully OCI compliant.
When using the containerd image store, this code is not used. That
exporter will just use containerd's export method and should give us the
output we want for multi-arch images.
