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.

As of https://github.com/docker/swarmkit/pull/1607, swarmkit honors
global network plugins while allocating network resources.
This IT covers the e2e integration between libnetwork, swarmkit and

This fix tries to address the issue related to 24108 and 24790, and
also the case from 24620#issuecomment-233715656
The reason for the failure case in the above mentioned issues is that
currently Task names are actually indexed by Service Name
(`e.ServiceAnnotations.Name`)
To fix it, a pull request in swarmkit (swarmkit/pull/1193) has been
opened separately.
This fix adds the integration tests for the above mentioned issues.
Swarmkit revendoring is needed to completely fix the issues.
This fix fixes 24108.
This fix fixes 24790.

This fix tries to address the issue raised in 24538
where the error message is unclear when removing pre-defined networks:
```
docker network rm ingress
Error response from daemon: rpc error: code = 7 desc = 4vlxuzpk8bxdsxpyvkxluol5g is a pre-defined network and cannot be removed
```
This fix improve the error message so that if network's name is specified
in the `RemoveNetwork`, then error message will contain the name and the ID
(instead of just an ID):
```
docker network rm ingress
Error response from daemon: rpc error: code = 7 desc = ingress (4vlxuzpk8bxdsxpyvkxluol5g) is a pre-defined network and cannot be removed
```
An integration test has been added to cover the changes.
This fix fixes 24538.

The swarm scope network connected containers with autostart enabled
there was a dependency problem with the cluster to be initialized before
we can autostart them. With the current container restart code happening
before cluster init, these containers were not getting autostarted
properly. Added a fix to delay the container start of those containers
which has atleast one swarm scope endpoint to until after the cluster is
initialized.

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 is an attempt to fix the flaky test of TestSwarmNodeTaskListFilter in 25029.
Basically this fix adds a check to wait until 3 containers has already up,
before processing `node tasks ...`.

manager/worker role into a single opaque string.
Adds a docker swarm join-token subcommand to inspect and rotate the

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`.
