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.

This adds the `--live-restore` option to the documentation.
Also synched usage description in the documentation
with the actual description, and re-phrased some
flag descriptions to be a bit more consistent.

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.

The path here should be absolute, else it would
deem it as volume name.
Also link to release page to contain static binary,
the old link not work, because it is just used to
install docker in os distro, it can not be used
as static binary directly.
