This PR adds support for running regular containers to be connected to
swarm mode multi-host network so that:
- containers connected to the same network across the cluster can
discover and connect to each other.
- Get access to services(and their associated loadbalancers)
connected to the same network

During image pulls on docker service create, logs will only show status
updates and updates every 1 second on long-running actions like
downloading and extracting. Adds golang.org/x/time/rate as dependency.
Ports docker/swarmkit#1352 to docker/docker.

In cases there are failures in task start, swarmkit might be trying to
restart the task again in the same node which might keep failing. This
creates a race where when a failed task is getting removed it might
remove the associated network while another task for the same service
or a different service but connected to the same network is proceeding
with starting the container knowing that the network is still
present. Fix this by reacting to `ErrNoSuchNetwork` error during
container start by trying to recreate the managed networks. If they
have been removed it will be recreated. If they are already present
nothing bad will happen.

Unlike `docker run -v..`, `docker service create --mount`
does not allow bind-mounting non-existing host paths.
This adds validation for the specified `source`, and
produces an error if the path is not found on the
host.

This is intended as a minor fix for 1.12.1 so that task creation doesn't
do unexpected things when the user supplies erroneous paths.
In particular, because we're currently using hostConfig.Binds to setup
mounts, if a user uses an absolute path for a volume mount source, or a
non-absolute path for a bind mount source, the engine will do the
opposite of what the user requested since all absolute paths are
treated as binds and all non-absolute paths are treated as named
volumes.
Fixes#25253

Context cancellations were previously causing `Prepare` to fail
completely on re-entrant calls. To prevent this, we filtered out cancels
and deadline errors. While this allowed the service to proceed without
errors, it had the possibility of interrupting long pulls, causing the
pull to happen twice.
This PR forks the context of the pull to match the lifetime of
`Controller`, ensuring that for each task, the pull is only performed
once. It also ensures that multiple calls to `Prepare` are re-entrant,
ensuring that the pull resumes from its original position.

Ensure that cancellation of a pull propagates rather than continuing to
container creation. This ensures that the `Prepare` method is properly
re-entrant.

In the API:
`Writable` changed to `ReadOnly`
`Populate` changed to `NoCopy`
Corresponding CLI options updated to:
`volume-writable` changed to `volume-readonly`
`volume-populate` changed to `volume-nocopy`

In order to keep a little bit of "sanity" on the API side, validate
hostname only starting from v1.24 API version.

Swarm was putting volume type mounts into the container config's
"Volumes" field, but really these need to go into "Binds".
"Volumes" is only for normal "-v /foo" volumes, not named volumes or
anything else.

This warning appears in the course of normal use of swarm mode. Since
it's meant more as an internal TODO than something which should be
exposed to a user, remove the log message.

As described in our ROADMAP.md, introduce new Swarm management API
endpoints relying on swarmkit to deploy services. It currently vendors
docker/engine-api changes.
This PR is fully backward compatible (joining a Swarm is an optional
feature of the Engine, and existing commands are not impacted).
