--group-add was used for specifying groups for both service create
and service update. For create it was confusing since we don't have
an existing set of groups. Instead I added --group to create, and
moved --group-add to service update only, like --group-rm
This deals with issue 27646

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.

In #23614 `docker inspect` was semantically enhanced to inspect "everything".
Therefore moving its logic to `_docker_container_inspect` was not correct.
This commit moves it back to its original top-level location (`_docker_inspect`)
so that it can be called by `_docker_{container,image}_inspect` and others (will
be added in follow-up PRs).
Parameterization was added in order to get caller-specific behavior.

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.
