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.

Update documentation to account for the changes in #24952.
docs/swarm/swarm-tutorial/rolling-update.md doesn't need any changes,
but the CLI reference pages should show the current help text.
drain-node.md no longer needs to specify --update-parallelism 1 in its
example.

When updates happen, the current behavior is to kill all running
instances and dispatch new tasks. Common use cases for container updates
involve small numbers of containers, meaning the app will go down on
most updates. Setting parallelism to 1 ensures that at most one task
will go down during the update. Services with higher replica counts can
increase this number accordingly to meet their needs.

f5e1f6f688 replaced "secrets"
with "join tokens", which also removed the "auto-accept"
policy.
This removes some remaining references to those features.
Note that there are other references, but those
are already addressed in another pull request.

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.

Swarm join has been changed in f5e1f6f688,
removing various options and the "node accept" command.
This removes the removed options from the completion
scripts.
NOTE: a new command ("docker swarm join-token") was
also added, but is not part of this commit.

In 24823, `swarm join` has been updated to take a `--token`
flag and flag `--manager` has been removed. Though in errNoManager()
the error message still use the old description.
This fix update the error message in errNoManager() and conforms
to the current available flags.
This fix is related to 24823.

Simplifies the mount option usage by providing common aliases for
`source` and `target`. The default mount type is now volume.
