This fix is a follow up to #27567 based on:
https://github.com/docker/docker/pull/27567#issuecomment-259295055
In #27567, `--dns-options` has been added to `service create/update`,
together with `--dns` and `--dns-search`. The `--dns-opt` was used
in `docker run`.
This fix add `--dns-option` (not `--dns-options`) to `docker run/create`, and hide
`--dns-opt`. It is still possible to use `--dns-opt` with
`docker run/create`, though it will not show up in help output.
This fix change `--dns-options`to --dns-option` for `docker service create`
and `docker service update`.
This fix also updates the docs and bash/zsh completion scripts.

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.

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.

This fix tries to add a flag `--stop-timeout` to specify the timeout value
(in seconds) for the container to stop before SIGKILL is issued. If stop timeout
is not specified then the default timeout (10s) is used.
Additional test cases have been added to cover the change.
This fix is related to #22471. Another pull request will add `--shutdown-timeout`
to daemon for #22471.

Allow passing --storage-opt size=X to docker create/run commands
for the `overlay2` graphriver.
The size option is only available if the backing fs is xfs that is
mounted with the `pquota` mount option.
The user can pass any size less then the backing fs size.

Add the swapMemorySupport requirement to all tests related to the OOM killer. The --memory option has the subtle side effect of defaulting --memory-swap to double the value of --memory. The OOM killer doesn't kick in until the container exhausts memory+swap, and so without the memory swap cgroup the tests will timeout due to swap being effectively unlimited.
Document the default behavior of --memory-swap in the docker run man page.

This allows a user to specify explicitly to enable
automatic copying of data from the container path to the volume path.
This does not change the default behavior of automatically copying, but
does allow a user to disable it at runtime.

Following #19995 and #17409 this PR enables skipping userns re-mapping
when creating a container (or when executing a command). Thus, enabling
privileged containers running side by side with userns remapped
containers.
The feature is enabled by specifying ```--userns:host```, which will not
remapped the user if userns are applied. If this flag is not specified,
the existing behavior (which blocks specific privileged operation)
remains.

We cannot rely on the tar command for this type of operation because tar
versions, flags, and functionality can very from distro to distro.
Since this is in the container execution path it is not safe to have
this as a dependency from dockers POV where the user cannot change the
fact that docker is adding these pre and post mount commands.
