This fix tries to address the proposal raised in 27921 and add
`--cpus` flag for `docker run/create`.
Basically, `--cpus` will allow user to specify a number (possibly partial)
about how many CPUs the container will use. For example, on a 2-CPU system
`--cpus 1.5` means the container will take 75% (1.5/2) of the CPU share.
This fix adds a `NanoCPUs` field to `HostConfig` since swarmkit alreay
have a concept of NanoCPUs for tasks. The `--cpus` flag will translate
the number into reused `NanoCPUs` to be consistent.
This fix adds integration tests to cover the changes.
Related docs (`docker run` and Remote APIs) have been updated.
This fix fixes 27921.

Allow built images to be squash to scratch.
Squashing does not destroy any images or layers, and preserves the
build cache.
Introduce a new CLI argument --squash to docker build
Introduce a new param to the build API endpoint `squash`
Once the build is complete, docker creates a new image loading the diffs
from each layer into a single new layer and references all the parent's
layers.

To load an image from a tar file, you can specify
the tar file in the -i/--input option:
docker load -i image_1.tar
or using stdin:
docker load < image_1.tar
cat image_1.tat | docker load
If the image file isn't given the `docker load`
command gets stuck.
To avoid that, the load makes sure the CLI input is
not a terminal or the `--input` option was set.
If not then an error message is shown.

containers may specify these cgroup values at runtime. This will allow
processes to change their priority to real-time within the container
when CONFIG_RT_GROUP_SCHED is enabled in the kernel. See #22380.
Also added sanity checks for the new --cpu-rt-runtime and --cpu-rt-period
flags to ensure that that the kernel supports these features and that
runtime is not greater than period.
Daemon will support a --cpu-rt-runtime flag to initialize the parent
cgroup on startup, this prevents the administrator from alotting runtime
to docker after each restart.
There are additional checks that could be added but maybe too far? Check
parent cgroups to ensure values are <= parent, inspecting rtprio ulimit
and issuing a warning.

Currently, there's no way to restart the tasks of a service without
making an actual change to the service. This leads to us giving awkward
workarounds as in
https://github.com/docker/docker.github.io/pull/178/files, where we tell
people to scale a service up and down to restore balance, or make
unnecessary changes to trigger a restart.
This change adds a --force option to "docker service update", which
forces the service to be updated even if no changes require that.
Since rolling update parameters are respected, the user can use
"docker service --force" to do a rolling restart. For example, the
following is supported:
docker service update --force --update-parallelism 2 \
--update-delay 5s myservice
Since the default value of --update-parallelism is 1, the default
behavior is to restart the service one task at a time.

This adds support for two enhancements to swarm service rolling updates:
- Failure thresholds: In Docker 1.12, a service update could be set up
to either pause or continue after a single failure occurs. This adds
an --update-max-failure-ratio flag that controls how many tasks need to
fail to update for the update as a whole to be considered a failure. A
counterpart flag, --update-monitor, controls how long to monitor each
task for a failure after starting it during the update.
- Rollback flag: service update --rollback reverts the service to its
previous version. If a service update encounters task failures, or
fails to function properly for some other reason, the user can roll back
the update.
SwarmKit also has the ability to roll back updates automatically after
hitting the failure thresholds, but we've decided not to expose this in
the Docker API/CLI for now, favoring a workflow where the decision to
roll back is always made by an admin. Depending on user feedback, we may
add a "rollback" option to --update-failure-action in the future.

This fix tries to address the issue raised in 24392 where
labels with duplicate keys exist in `docker info`, which
contradicts with the specifications in the docs.
The reason for duplicate keys is that labels are stored as
slice of strings in the format of `A=B` (and the input/output).
This fix tries to address this issue by checking conflict
labels when daemon started, and remove duplicate labels (K-V).
The existing `/info` API has not been changed.
An additional integration test has been added to cover the
changes in this fix.

This fix tries to address the issue raised in 25855 where the command
`docker deploy` can only accept a STACK without extension of `.dab`.
In other words, `docker deploy hellojavaee.dab` gives an error:
```
Bundle hellojavaee.dab.dab not found. Specify the path with --file
```
This fix updates the way namespace STACK is taken so that in case
`STACK.dab` is provided with `docker deploy`:
```
$ docker deploy STACK.dab
```
The `STACK` is used as namespace (instead of `STACK.dab`).
NOTE: This fix will only allows `.dab` extension in namespace, because
it is not possible to have a namespace with `.` in the middle. In other
words, a namespace `hello.java.ee` will not work anyway (whether the file
`hello.java.ee` exists or not).
An additional integration test has been added to cover the changes.

This fix is related to 27049 and 27047. For `--label` flag, if string slice is
used (like 27047), then quote can not be used in command and will result in
an error :
```
line 1, column 14: bare " in non-quoted-field
```
The issue 27047 has been fixed by 27049.
Recently I found out that both `docker network create --label` and `docker volume create --label`
still use string slice and will return the same error when quotes are used.
This fix fixes `docker network create --label` and `docker volume create --label`
by using `ListOpt` (as 27049) as well.

The formatter.ContainerStats struct exposes its Mutex.
This is a bad design and should be fixed.
To fix that, I separated the statistics
attributes from ContainerStats to StatsEntry and
hid the mutex. Notice that the mutex protects both
the `err` field and the statistics attributes.
Then, implemented SetStatistics, SetError, GetStatistics
and GetError to avoid races.
Moreover, to make this less granular, I decided to
replace the read-write mutex with the regular mutex and
to pass a StatsEntry slice to formatter.ContainerStatsWrite

When `docker inspect` is invoked, it is possible to pass a flag of
`-s` for container types to display size information. If `-s` is used
for non-container types then a warning `WARNING: --size ignored for volume`
will show up.
However, currently `WARNING: --size ignored for volume` will show up even
when `-s` is not passed to `docker inspect` for non-container types.
This fix fixes this issue by checking if `-s` has been passed or not (`getSize`).
Also, since image inspect does not support `-s`, `IsSizeSupported` has been changed
to false for images.
