Hostnames are not supported for now because libnetwork can't use them
for overlay networking yet.

There are currently problems with "swarm init" and "swarm join" when an
explicit --listen-addr flag is not provided. swarmkit defaults to
finding the IP address associated with the default route, and in cloud
setups this is often the wrong choice.
Introduce a notion of "advertised address", with the client flag
--advertise-addr, and the daemon flag --swarm-default-advertise-addr to
provide a default. The default listening address is now 0.0.0.0, but a
valid advertised address must be detected or specified.
If no explicit advertised address is specified, error out if there is
more than one usable candidate IP address on the system. This requires a
user to explicitly choose instead of letting swarmkit make the wrong
choice. For the purposes of this autodetection, we ignore certain
interfaces that are unlikely to be relevant (currently docker*).
The user is also required to choose a listen address on swarm init if
they specify an explicit advertise address that is a hostname or an IP
address that's not local to the system. This is a requirement for
overlay networking.
Also support specifying interface names to --listen-addr,
--advertise-addr, and the daemon flag --swarm-default-advertise-addr.
This will fail if the interface has multiple IP addresses (unless it has
a single IPv4 address and a single IPv6 address - then we resolve the
tie in favor of IPv4).
This change also exposes the node's externally-reachable address in
docker info, as requested by #24017.
Make corresponding API and CLI docs changes.

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 changes `docker swarm help` to be consistent with capitals
and removes full stops.
Before:
```
Commands:
init Initialize a Swarm.
join Join a Swarm as a node and/or manager.
update update the Swarm.
leave Leave a Swarm.
inspect Inspect the Swarm
```
After:
```
Commands:
init Initialize a Swarm
join Join a Swarm as a node and/or manager
update Update the Swarm
leave Leave a Swarm
inspect Inspect the Swarm
```

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).
