This test case checks that a container created before start
of the currently running dockerd can be exported (as reported
in #36561). To satisfy this condition, either a pre-existing
container is required, or a daemon restart after container
creation.

I am not quite sure why but this test is sometimes failing like this:

To eliminate some possible failures (like ignoring stderr from `cat` or
its exit code), let's use container.Exec() to read a file from a container.

As mentioned in commit 9e31938, test cases that use t.Parallel()
and start a docker daemon might step on each other toes as they
try to configure iptables during startup, resulting in flaky tests.
To avoid this, --iptables=false should be used while starting daemon.

This fix addresses `expected` vs `actual` in integration tests
so that they match `assert.Equal(t, expected, actual)`

This fix adds several improvement:
1. No need for explicit ContainerRemove as it has been handled in setupTest()
2. Added `container.WithImage` helper function and used it in commit tests.

The canonical import comment was added some time ago, though several
newly added files do not have the comment. This fix adds the missing
canonical import comment to files in integration tests

This fix is a minor enhancement to replace several ContainerCreate with
helper funcs of `container.Create` in tests.

This fix moves helper functions containerIsStopped and
containerIsInState to integration/internal/container,
so that they could be used outside of integration/container.

1. Use integration/internal/exec, removing the getContainerSysFSValue().
2. Avoid repeating magic numbers, use a variable for those.
3. Fix order of arguments to assert.Equal (first "expected", then "actual").

An implementation of exec in TestUpdateCPUQUota had a few issues,
including resource leaking and calling both ContainerExecAttach and
ContainerExecRun. The last one makes the test flaky:
update_linux_test.go:136: expected cgroup value 20000, got: Error: Exec
command f923baf709525f6b38f6511126addc5d9bb88fb477eeca1c22440551090fa2bb
is already running
Fix by using the integration/internal/exec package.
While at it, use require/assert to further improve code readability.

When tailing a container log, if the log file is empty it will cause the
log stream to abort with an unexpected `EOF`.
Note that this only applies to the "current" log file as rotated files
cannot be empty.
This fix just skips adding the "current" file the log tail if it is
empty.

To help creating/running/… containers using the client for test integration.
This should make test more readable and reduce duplication a bit.
Usage example
```
// Create a default container named foo
id1 := container.Create(t, ctx, client, container.WithName("foo"))
// Run a default container with a custom command
id2 := container.Run(t, ctx, client, container.WithCmd("echo", "hello world"))
```

Both names have no real sense, but one allows to make sure these packages
aren't used outside of `integration`.

When the daemon restores containers on daemon restart, it syncs up with
containerd to determine the existing state. For stopped containers it
then removes the container metadata from containerd.
In some cases this is not handled properly and causes an error when
someone attempts to start that container again.
In particular, this case is just a bad error check.
