This parameter controls the order of operations when rolling out an
update task. Either the old task is stopped before starting the new one,
or the new task is started first, and the running tasks will briefly
overlap.
This commit adds Rollout to the API, and --update-order / --rollback-order
flags to the CLI.

Change "service create" and "service update" to wait until the creation
or update finishes, when --detach=false is specified. Show progress bars
for the overall operation and for each individual task (when there are a
small enough number of tasks), unless "-q" / "--quiet" is specified.

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)

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 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`.

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.

Rather than conflict with the unexposed task model, change the names of
the object-oriented task display to `docker <object> ps`. The command
works identically to `docker service tasks`. This change is superficial.
This provides a more sensical docker experience while not trampling on
the task model that may be introduced as a top-level command at a later
date.
The following is an example of the display using `docker service ps`
with a service named `condescending_cori`:
```
$ docker service ps condescending_cori
ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE
e2cd9vqb62qjk38lw65uoffd2 condescending_cori.1 condescending_cori alpine Running 13 minutes ago Running 6c6d232a5d0e
```
The following shows the output for the node on which the command is
running:
```console
$ docker node ps self

This changes the default behavior so that rolling updates will not
proceed once an updated task fails to start, or stops running during the
update. Users can use docker service inspect --pretty servicename to see
the update status, and if it pauses due to a failure, it will explain
that the update is paused, and show the task ID that caused it to pause.
It also shows the time since the update started.
A new --update-on-failure=(pause|continue) flag selects the
behavior. Pause means the update stops once a task fails, continue means
the old behavior of continuing the update anyway.
In the future this will be extended with additional behaviors like
automatic rollback, and flags controlling parameters like how many tasks
need to fail for the update to stop proceeding. This is a minimal
solution for 1.12.
