Kernel memory is not allowed to be updated if container is
running, it's not actually a precise kernel limitation.
Before kernel version 4.6, kernel memory will not be accounted
until kernel memory limit is set, if a container created with
kernel memory initialized, kernel memory is accounted as soon
as process created in container, so kernel memory limit update
is allowed afterward. If kernel memory is not initialized,
kernel memory consumed by processes in container will not be
accounted, so we can't update the limit because the account
will be wrong.
So update kernel memory of a running container with kernel memory
initialized is allowed, we should soften the limitation by docker.

The current behavior of `docker swarm init` is to set up a swarm that
has no secret for joining, and does not require manual acceptance for
workers. Since workers may sometimes receive sensitive data such as pull
credentials, it makes sense to harden the defaults.
This change makes `docker swarm init` generate a random secret if none
is provided, and print it to the terminal. This secret will be needed to
join workers or managers to the swarm. In addition to improving access
control to the cluster, this setup removes an avenue for
denial-of-service attacks, since the secret is necessary to even create
an entry in the node list.
`docker swarm init --secret ""` will set up a swarm without a secret,
matching the old behavior. `docker swarm update --secret ""` removes the
automatically generated secret after `docker swarm init`.

In #24159, the title field of `docker node ls` has been
changed from NAME to HOSTNAME. However, in the docs the
NAMEs are still used for the output of `docker node ls`.
This fix updates docs so that NAME field is changed to
HOSTNAME for all `docker node ls`.
This fix is related to #24159 and #24090.

The --auto-accept documentation currently says that both worker and
manager nodes are automatically accepted by default. Correct it.

For consistency with other filters (such as
"is-official"), this renames the desired_state
filter to "desired-state".

This deprecates the shorthand '-h', because we don't mention it as an option,
and it conflicts with the 'docker create -h/--hostname' option, so cannot be
used for all commands consistently.
This also removes the (single-dash) '-help' option. The single-dash variant was
marked "deprecated" in version 1.5.0 (basically, since it was added in
a2b529ead21e6ab9eafcb1b1d2437c725c43a06a), but still kept around to
prevent '-help' being treated as '-h -e -l -p', causing confusing
warnings.

The reason why the issue occurs is because sh parses the first argument after -c as the whole script to execute.
Everything after isn't executed as one might expect.
When working on the 'fix' I found out the same fix is also done in commit 2af7c5cfe24b4c8e931f751979b5e69e20ba77e2, except only for one occurrence.
