The --name flag was inadvertently added to
docker service update, but is not supported,
as it has various side-effects (e.g., existing
tasks are not renamed).
This removes the flag from the service update
command.

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.

The following sentences (introduced in v1.11 via #21160) were misleading for Swarm mode services (>= v1.12)
For networks backed by multi-host network driver, such as Overlay,
this command also shows the container endpoints in other hosts in the
cluster. These endpoints are represented as "ep-{endpoint-id}" in the output.

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.

cURL 7.50 changed the validation for URL's
when using socket connections. cURL 7.4x
did not expect a hostname, whereas cURL
7.5x and above _requires_ a hostname.
See https://github.com/curl/curl/issues/936
This updates the example to take both
versions into account, because cURL 7.4x
is still widely used by distros.

This fix tries to address the issue raised in 25545 where
volume options at the creation time is not showed up
in `docker volume inspect`.
This fix adds the field `Options` in `Volume` type and
persist the options in volume db so that `volume inspect`
could display the options.
This fix adds a couple of test cases to cover the changes.

Keeping the current behavior for exec, i.e., inheriting
variables from main process. New variables will be added
to current ones. If there's already a variable with that
name it will be overwritten.

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.
