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.

Adds log driver support for service creation and update. Add flags
`--log-driver` and `--log-opt` to match `docker run`. Log drivers are
configured per service.

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).
