After dicussing with maintainers, it was decided putting the burden of
providing the full cap list on the client is not a good design.
Instead we decided to follow along with the container API and use cap
add/drop.
This brings in the changes already merged into swarmkit.

In order to run tests at mips64el device.
Now official-images has supported the following images for mips64el.
buildpack-deps:stretch
buildpack-deps:buster
debian:stretch
debian:buster
But official-images does not support the following images for mips64el.
debian:jessie
buildpack-deps:jessie

If the container specified in `--volumes-from` did not exist, the
API returned a 404 status, which was interpreted by the CLI as the
specified _image_ to be missing (even if that was not the case).
This patch changes these error to return a 400 (bad request);
Before this change:
# make sure the image is present
docker pull busybox
docker create --volumes-from=nosuchcontainer busybox
# Unable to find image 'busybox:latest' locally
# latest: Pulling from library/busybox
# Digest: sha256:95cf004f559831017cdf4628aaf1bb30133677be8702a8c5f2994629f637a209
# Status: Image is up to date for busybox:latest
# Error response from daemon: No such container: nosuchcontainer
After this change:
# make sure the image is present
docker pull busybox
docker create --volumes-from=nosuchcontainer busybox
# Error response from daemon: No such container: nosuchcontainer

Usage: DOCKER_BUILD_ARGS="--build-arg CONTAINERD_COMMIT=master --build-arg RUNC_COMMIT=master" DOCKER_EXPERIMENTAL=1 TEST_SKIP_INTEGRATION_CLI=1 make test-integration
Depends on containerd master (v1.4) and runc master (v1.0.0-rc91).
Currently `TEST_SKIP_INTEGRATION_CLI=1` must be specified.

The initial implementation followed the Swarm API, where
PidsLimit is located in ContainerSpec. This is not the
desired place for this property, so moving the field to
TaskTemplate.Resources in our API.
A similar change should be made in the SwarmKit API (likely
keeping the old field for backward compatibility, because
it was merged some releases back)

The test case panics like that:
> build_test.go:381: assertion failed: 3 (int) != 1 (int)
> panic: runtime error: index out of range [2] with length 1 [recovered]
> panic: runtime error: index out of range [2] with length 1
The fix is trivial.

Support for PidsLimit was added to SwarmKit in docker/swarmkit/pull/2415,
but never exposed through the Docker remove API.
This patch exposes the feature in the repote API.

When a container is left running after the daemon exits (e.g. the daemon
is SIGKILL'd or crashes), it should stop any running containers when the
daemon starts back up.
What actually happens is the daemon only sends the container's
configured stop signal and does not check if it has exited.
If the container does not actually exit then it is left running.
This fixes this unexpected behavior by calling the same function to shut
down the container that the daemon shutdown process does.

This removes the use of the old distribution code in the plugin packages
and replaces it with containerd libraries for plugin pushes and pulls.
Additionally it uses a content store from containerd which seems like
it's compatible with the old "basicBlobStore" in the plugin package.
This is being used locally isntead of through the containerd client for
now.

This enables image lookup when creating a container to fail when the
reference exists but it is for the wrong platform. This prevents trying
to run an image for the wrong platform, as can be the case with, for
example binfmt_misc+qemu.

Switch to moby/sys/mount and mountinfo. Keep the pkg/mount for potential
outside users.
This commit was generated by the following bash script:
```

Metrics collectors generally don't need the daemon to prime the stats
with something to compare since they already have something to compare
with.
Before this change, the API does 2 collection cycles (which takes
roughly 2s) in order to provide comparison for CPU usage over 1s. This
was primarily added so that `docker stats --no-stream` had something to
compare against.
Really the CLI should have just made a 2nd call and done the comparison
itself rather than forcing it on all API consumers.
That ship has long sailed, though.
With this change, clients can set an option to just pull a single stat,
which is *at least* a full second faster:
Old:
```
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=false > /dev/null
2>&1
real0m1.864s
user0m0.005s
sys0m0.007s
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=false > /dev/null
2>&1
real0m1.173s
user0m0.010s
sys0m0.006s
```
New:
```
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=true > /dev/null
2>&1
real0m0.680s
user0m0.008s
sys0m0.004s
time curl --unix-socket
/go/src/github.com/docker/docker/bundles/test-integration-shell/docker.sock
http://./containers/test/stats?stream=false\&one-shot=true > /dev/null
2>&1
real0m0.156s
user0m0.007s
sys0m0.007s
```
This fixes issues with downstreams ability to use the stats API to
collect metrics.
