The `--host-add` flag adds a new `host:ip` mapping. Even though
adding an entry is idempotent (adding the same mapping multiple
times does not update the service's definition), it does not
_update_ an existing mapping with a new IP-address (multiple
IP-addresses can be defined for a host).
This patch removes the "or update" part from the flag's
description.

This fix made several updates:
1. Update opts.MemBytes so that default value will not show up.
The reason is that in case a default value is decided by daemon,
instead of client, we actually want to not show default value.
2. Move `docker run/create/build` to use opts.MemBytes for `--shm-size`
This is to bring consistency between daemon and docker run

This fix tries to address the issue raised in 29291 where
the output of `--replicas` in `service create/update`:
```
--replicas uint Number of tasks (default none)
```
is misleading. User might incorrectly assume the number of replicas
would be `0` (`none`) by default, while the actual default is `1`.
The issue comes from the fact that some of the default values are
from daemon and it is not possible for client to find out the default
value.
In this case, it might be better to just simply not displaying `(default none)`.
This fix returns "" for `Uint64Opt` so that `(default none)` is hidden.
In addition to `--replicas`, this fix also changes
`--restart-delay`, `--restart-max-attempts`, `--stop-grace-period`,
`--health-interval`, `--health-timeout`, and `--restart-window`
in a similiar fashion.
New Output:
```
--health-interval duration Time between running the check (ns|us|ms|s|m|h)
--health-timeout duration Maximum time to allow one check to run (ns|us|ms|s|m|h)
...
--replicas uint Number of tasks
...
--restart-delay duration Delay between restart attempts (ns|us|ms|s|m|h)
--restart-max-attempts uint Maximum number of restarts before giving up
--restart-window duration Window used to evaluate the restart policy (ns|us|ms|s|m|h)
...
--stop-grace-period duration Time to wait before force killing a container (ns|us|ms|s|m|h)
```

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 is based on the comment:
https://github.com/docker/docker/pull/28147#discussion_r86996347
Previously the output string of the `DurationOpt` is `duration-ptr`
and `Uint64Opt` is `uint64-ptr`. While it is clear to developers,
for a normal user `-ptr` might not be very informative.
On the other hand, the default value of `DurationOpt` and `Uint64Opt`
has already been quite informative: `none`. That means if no flag
provided, the value will be treated as none.
(like a ptr with nil as the default)
For that reason this fix removes the `-ptr`.
Also, the output in the docs of `service create` has been quite
out-of-sync with the true output. So this fix updates the docs
to have the most up-to-date help output of `service create --help`.

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.

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.
