As of now promoting (or demoting) a node that has its role
left unchanged will always print a successful message.
This PR fixes the issue by matching the behavior on swarmkit's
swarmctl command and printing a message when desired role is
the current role of the node.
As a result this also avoids calling update when it is not
necessary.

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.

As described in our ROADMAP.md, introduce new Swarm management commands
to call to the corresponding API endpoints.
This PR is fully backward compatible (joining a Swarm is an optional
feature of the Engine, and existing commands are not impacted).
