When starting docker daemons for swarm testing, we disable iptables
and use lo for communication (in order to avoid network conflicts).
The problem is, these options are lost on restart, that can lead
to any sorts of network conflicts and thus connectivity issues
between swarm nodes.
Fix this. This does not fix issues with swarm test failures, but
it seems they appear are less often after this one.

1. After running d.Cmd(), in case an error is returned, it makes sense
to print command output, as its stderr may contain a clue about what
went wrong. This is by no means complete, just as far as I could go.
2. In case the comment in c.Assert is a constant string, it's better
to provide it as a comment which will be printed.
3. An arbitrary string should not be passed on to a function expecting
%-style formatting. Use %s to fix this.
4. Print the output string before transformation, not after.
5. Unify the output format (drop "out:" prefix").

It is wrong to pass an arbitrary string to a function expecting
%-style formatting. One solution would be to replace any % with %%,
but it's easier to just do what this patch does.

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

Fixes previously flaky TestAPISwarmRaftQuorum.
In the test we are shutting down 2 of 3 nodes, all of which are managers.
When this happens the remaining node prepares to step down from being
a leader because there is no longer an active quorum. This test was
written before that change was implemented, and assumes that the
remaining node can still handle requests to create a service (it can't)
There was further flakiness depending on whether or not the node has
stepped down or was in the process of doing so. Fix this by waiting
for the node to completely step down and checking to see if it errors
out like it should.

otherwise if the user gets the info from the API, makes a non-CA related change,
then updates, swarm will interpret this as the user trying to remove the signing
key from the swarm. We are redacting due to usability reasons, not because
the signing cert is secret. The signing KEY is secret, hence it's redacted.

This fix tries to add a `scope` in the query of `/networks/<id>`
(`NetworkInspect`) so that in case of duplicate network names,
it is possible to locate the network ID based on the network
scope (`local`, 'swarm', or `global`).
Multiple networks might exist in different scopes, which is a legitimate case.
For example, a network name `foo` might exists locally and in swarm network.
However, before this PR it was not possible to query a network name `foo`
in a specific scope like swarm.
This fix fixes the issue by allowing a `scope` query in `/networks/<id>`.
Additional test cases have been added to unit tests and integration tests.

This test shuts down two out of three managers and then asserts that the
swarm has a leader. A swarm that lost quorum won't necessarily have a
leader, and in this case only has one because the old leader is still
around. Soon SwarmKit will be changed so the leader gives up leadership
when quorum is lost. This will avoid confusing situations, like
read-only APIs succeeding, while ones that write to Raft hang.

This fix tries to address the issue raised in 30242 where the `Scope`
field always changed to `swarm` in the ouput of `docker network ls/inspect`
when duplicate networks name exist.
The reason for the issue was that `buildNetworkResource()` use network name
(which may not be unique) to check for the scope.
This fix fixes the issue by always use network ID in `buildNetworkResource()`.
A test has been added. The test fails before the fix and passes after the fix.

This removes the need to check for error and make the intent more
clear : I want a deamon with busybox loaded on it — if an error occur
it should fail the test, but it's not the test code that has the
responsability to check that.

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.
