1. After running d.Cmd(), in case an error is returned, it makes sense
to print command output, as its stderr may contain a clue about what
went wrong. This is by no means complete, just as far as I could go.
2. In case the comment in c.Assert is a constant string, it's better
to provide it as a comment which will be printed.
3. An arbitrary string should not be passed on to a function expecting
%-style formatting. Use %s to fix this.
4. Print the output string before transformation, not after.
5. Unify the output format (drop "out:" prefix").

It is wrong to pass an arbitrary string to a function expecting
%-style formatting. One solution would be to replace any % with %%,
but it's easier to just do what this patch does.

This test is testing if any "no space left on device" errors
that occur during `docker pull` will not be masked by other
errors. To test for this, a new loopback-device was created,
and used as `--data-dir` ("/var/lib/docker").
However, `/var/lib/docker` is used for storing various
other things, including a `cache.db` database, used by
BuildKit, which is created during startup of the daemon.
Creation of that file failed (due to `--data-dir` path
being on a mount with limited size), which caused daemon
start to fail before the test was able to run.
This patch changes the size-limited mount to be used for
the storage-driver directory only, so that the test is
not affected by other parts of the code attempting to
write files in it.
To have a predictable path; the daemon used in this test
is configured to use the `vfs` storage-driver.

There is no need to perform a separate losetup step; mount (even
the one in busybox!) is smart enough to set up a loopback device
all by itself (even without -o loop present!). More to say, while
doing this, it sets LO_FLAGS_AUTOCLEAR flag for the kernel to
delete the loopback device as soon as its fs is unmounted (this
is supposed to work since kernel 2.6.25).
Also, remove mount options (-t ext4, -o loop,rw) as they are
either defaults (rw) or mount is smart enough to figure out.
Leave -n so it won't do unnecessary write to container's /etc/mtab.
While at it, touch up some comments.

`TestCleanupMountsAfterDaemonAndContainerKill` was supposedly written
when the container mounts were visible from the host. Currently they
all live in their own mount namespace and the only visible mount is
the tmpfs one for shareable /dev/shm inside the container (i.e.
/var/lib/docker/containers/<ID>/shm), which will no longer be there
in case of `--default-ipc-mode private` is used, and so the test will
fail. Add a check if any container mounts are visible from the host,
and skip the test if there are none, as there's nothing to check.
`TestCleanupMountsAfterDaemonCrash`: fix in a similar way, keeping
all the other checks it does, and skipping the "mounts gone" check
if there were no mounts visible from the host.
While at it, also fix the tests to use `d.Kill()` in order to not
leave behind a stale `docker.pid` files.

Follow the conventions for namespace naming set out by other projects,
such as linuxkit and cri-containerd. Typically, they are some sort of
host name, with a subdomain describing functionality of the namespace.
In the case of linuxkit, services are launched in `services.linuxkit`.
In cri-containerd, pods are launched in `k8s.io`, making it clear that
these are from kubernetes.

The shutdown timeout for containers in insufficient on Windows. If the daemon is shutting down, and a container takes longer than expected to shut down, this can cause the container to remain in a bad state after restart, and never be able to start again. Increasing the timeout makes this less likely to occur.

This test tries to pull all the tags in the busybox repo and looks to see
if there were more than two images pulled. This was failing on
p/z due to the recent change to manifest lists, where one of the busybox
tags didn't have a p/z manifest in it's manifest list.
This error seems fine to me, so I changed the test to see if pull fails,
it fails with the "manifest not found" error.
Also switched from busybox -> alpine, because it has significantly less tags,
and the images are close in size.

These test cases cover various arguments for docker create/run --ipc
option, as well as daemon's --default-ipc-mode cli option and
configuration file parameter.
For the description of container IPC modes, see previous commit.
To run these:
TESTFLAGS='-check.f IpcMode' make test-integration-cli
[v2: simplify TestDaemonEvents(), add default-ipc-mode presense check]
[v3: add TestDaemonIpcModeVSRestart]
[v4: ipcmode test now uses client lib instead of CLI (except for exec)]
[v5: nitpicks in comments]
[v6: add test case for "none"; fix a typo; simplify TestDaemonEvents() more]

Before this patch, if the plugin's `config.json` is successfully removed
but the main plugin state dir could not be removed for some reason (e.g.
leaked mount), it will prevent the daemon from being able to be
restarted.
This patches changes this to atomically remove the plugin such that on
daemon restart we can detect that there was an error and re-try. It also
changes the logic so that it only logs errors on restore rather than
erroring out the daemon.
This also removes some code which is now duplicated elsewhere.

Because of argument order to assert, in case of fail, we'll get message
like:
... obtained string = "uid=100(test) gid=101(test)\n"
... expected string = "uid=100(test) gid=101(test) groups=101(test)\n"
But obtained string should be second one, not the first one. And
expected string should be first. Here's sample output from test above:
... Output: before restart 'uid=100(test) gid=101(test)
', after restart 'uid=100(test) gid=101(test) groups=101(test)
It's confusing, because expected order of strings in assertion is
reversed. What goes before restart - should be "expected string" and
what goes after - should be "obtained string".
