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.

A test failed expecting 200, but received -1, which is an err rc,
not an HTTP status code, so move these checks up.
Also log the output an not just check for a nil err.

Remove the swarm inspect command and use docker info instead to display
swarm information if the current node is a manager.

This renames the `rotate_xxx` flags to camelBack, for
consistency with other API query-params, such as
`detachKeys`, `noOverwriteDirNonDir`, and `fromImage`.
Also makes this flag accept a wider range of boolean
values ("0", "1", "true", "false"), and throw an error
if an invalid value is passed.

Implement the proposal from
https://github.com/docker/docker/issues/24430#issuecomment-233100121
Removes acceptance policy and secret in favor of an automatically
generated join token that combines the secret, CA hash, and
manager/worker role into a single opaque string.
Adds a docker swarm join-token subcommand to inspect and rotate the
tokens.

This is done in a hacky way as currently there is no better way.
Uses known implementation details about how tasks are scheduled to be
able to operate on the underlying container.
