Since 24237 has been merged, it is not necessary to require network
for swarm integration tests (`integration-cli/docker_api_swarm_test.go`)
any more.
This fix removes testRequires(c, Network) from swarm integration
tests.
This fix could be verified by disable networking, and all related
tests pass.
This fix is related to 24547, 24490, 24237.
This fix fixes 24547.

On Ubuntu and Debian there is a sysctl which allows to block
clone(CLONE_NEWUSER) via "sysctl kernel.unprivileged_userns_clone=0"
for unprivileged users that do not have CAP_SYS_ADMIN.
See: https://lists.ubuntu.com/archives/kernel-team/2016-January/067926.html
The DockerSuite.TestRunSeccompUnconfinedCloneUserns testcase fails if
"kernel.unprivileged_userns_clone" is set to 0:
docker_cli_run_unix_test.go:1040:
c.Fatalf("expected clone userns with --security-opt seccomp=unconfined
to succeed, got %s: %v", out, err)
... Error: expected clone userns with --security-opt seccomp=unconfined
to succeed, got clone failed: Operation not permitted
: exit status 1
So add a check and skip the testcase if kernel.unprivileged_userns_clone is 0.

Instead of using the bundles dir, which may be mounted in and ultimately
break if using b2d/d4mac/d4win. This makes it much easier to collect
test daemon logs and more natural for use d4mac/d4win users to run tests.

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

While testing #24510 I noticed that 32 bit syscalls were incorrectly being
blocked and we did not have a test for this, so adding one.
This is only tested on amd64 as it is the only architecture that
reliably supports 32 bit code execution, others only do sometimes.
There is no 32 bit libc in the buildpack-deps so we cannot build
32 bit C code easily so use the simplest assembly program which
just calls the exit syscall.

Ensure convergence before moving on with testing leader election
conditions. This reduce the flakiness of this test when run in different

If no restart delay is specified for a swarm service, the default
restart delay is 5 seconds. This is a reasonable value for actual
deployments - one example of where it's useful is that if a bad image is
specified, the orchestrator will wait 5 seconds between attempts to
restart it instead of restarting it in a tight loop.
In integration tests, this 5 second delay is dead time. The tests run
faster if the delay is reduced. Set it to 100 ms to avoid the waste of
time.
This appears to speed up a few tests:
DockerSwarmSuite.TestApiSwarmForceNewCluster 37.241s -> 34.323s
DockerSwarmSuite.TestApiSwarmRestartCluster 22.038s -> 15.545s
DockerSwarmSuite.TestApiSwarmServicesMultipleAgents 24.456s -> 19.853s
DockerSwarmSuite.TestApiSwarmServicesStateReporting 19.240s -> 10.049s
...a small step towards making the Swarm integration tests run in a
reasonable amount of time.
Also, change the update delay for the rolling update test from 8 seconds
to 4 seconds, which should be sufficient to differentiate between
batches of updated tasks. This reduces the runtime for
DockerSwarmSuite.TestApiSwarmServicesUpdate from 28s to 20s.

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 ...`.
This might fix 25029.

In `TestApiSwarmRestartCluster`, it's calling `checkClusterHealth`.
`checkClusterHealth` calls `d.info()`, which will return an error if
there is no cluster leader... problem is `checkClusterHealth` is doing a
nil error assertion w/o giving any time for a leader to be elected.
This moves the `d.info()` call into a `waitAndAssert` using the default
reconciliation timeout.
It also moves some other checks into a `waitAndAssert` to give the
cluster enough time to come back up.

Remove the swarm inspect command and use docker info instead to display

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.

There are currently problems with "swarm init" and "swarm join" when an
explicit --listen-addr flag is not provided. swarmkit defaults to
finding the IP address associated with the default route, and in cloud
setups this is often the wrong choice.
Introduce a notion of "advertised address", with the client flag
--advertise-addr, and the daemon flag --swarm-default-advertise-addr to
provide a default. The default listening address is now 0.0.0.0, but a
valid advertised address must be detected or specified.
If no explicit advertised address is specified, error out if there is
more than one usable candidate IP address on the system. This requires a
user to explicitly choose instead of letting swarmkit make the wrong
choice. For the purposes of this autodetection, we ignore certain
interfaces that are unlikely to be relevant (currently docker*).
The user is also required to choose a listen address on swarm init if
they specify an explicit advertise address that is a hostname or an IP
address that's not local to the system. This is a requirement for
overlay networking.
Also support specifying interface names to --listen-addr,
--advertise-addr, and the daemon flag --swarm-default-advertise-addr.
This will fail if the interface has multiple IP addresses (unless it has
a single IPv4 address and a single IPv6 address - then we resolve the
tie in favor of IPv4).
This change also exposes the node's externally-reachable address in
docker info, as requested by #24017.
Make corresponding API and CLI docs changes.
