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.

This fix is related to 30232 wherw `docker service ls`
does not show `PORTS` information like `docker service ps`.
This fix adds `PORTS` fields for services that publish
ports in ingress mode.
Additional unit tests cases have been updated.

This fix is an attempt to address
https://github.com/docker/docker/pull/28213#issuecomment-273840405
Currently when specify table format with table `--format "table {{.ID}}..."`,
the delimiter in the header section of the table is always `"\t"`.
That is actually different from the content of the table as the delimiter
could be anything (or even contatenated with `.`, for example):
```
$ docker service ps web --format 'table {{.Name}}.{{.ID}}' --no-trunc
NAME ID
web.1.inyhxhvjcijl0hdbu8lgrwwh7
\_ web.1.p9m4kx2srjqmfms4igam0uqlb
```
This fix is an attampt to address the skewness of the table when delimiter
is not `"\t"`.
The basic idea is that, when header consists of `table` key, the header section
will be redendered the same way as content section. A map mapping each
placeholder name to the HEADER entry name is used for the context of the header.
Unit tests have been updated and added to cover the changes.
This fix is related to #28313.

Remove forked reference package. Use normalized named values
everywhere and familiar functions to convert back to familiar
strings for UX and storage compatibility.
Enforce that the source repository in the distribution metadata
is always a normalized string, ignore invalid values which are not.
Update distribution tests to use normalized values.

This fix tries to improve the display of `docker service ls`
and adds `--format` flag to `docker service ls`.
In addition to `--format` flag, several other improvement:
1. Updates `docker stacks service`.
2. Adds `servicesFormat` to config file.
Related docs has been updated.

When UpdateStatus was not present, the empty values of the timestamps
would be present:
"UpdateStatus": {
"StartedAt": "0001-01-01T00:00:00Z",
"CompletedAt": "0001-01-01T00:00:00Z"
}
To fix this, make the timestamps pointers, so they can be set to nil
when they should not be shown.
Also make UpdateStatus itself a pointer, so an empty object does not
show up when there is no UpdateStatus.

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.

Currently, if the service mode is not "global", this code assumes that
Replicated is non-nil. This assumption may not be true in the future.
Instead of making the assumption, explicitly check that Replicated is
non-nil before using it.
Similarly, for limits and reservations, enclose methods that read from
Limits and Reservations within checks that those fields are non-nil.

Allows the user to use `pretty` as the format string.
This enables users to put custom format options into their CLI config
just like is supported for `docker ps` and `docker images`
