Following #22729, enable to dynamically reload/remove the daemon
authorization plugins (via standard reloading mechanism).
https://docs.docker.com/engine/reference/commandline/daemon/#daemon-
configuration-file
Daemon must store a reference to the authorization middleware to refresh
the plugin on configuration changes.

Component: engine
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.

This fixes the hard coded restriction for non-linux platforms to v2 registries. Previously, the check was above the flag parsing, which would overwrite the hard coded value and prevent correct operation. This change also removes the related daemon flag from Windows to avoid confusion, as it has no meaning when the value is going to always be hard coded to true.

Unix sockets are limited to 108 bytes. As a result, we need to be
careful in not using exec-root as the parent directory for pluginID
(which is already 64 bytes), since it can result in socket path names
longer than 108 bytes. Use /tmp instead. Before this change, setting:
- dockerd --exec-root=/go/src/github.com/do passes
- dockerd --exec-root=/go/src/github.com/doc fails
After this change, there's no failure.
Also, write a volume plugins test to verify that the plugins socket
responds.

This adds an `--oom-score-adjust` flag to the daemon so that the value
provided can be set for the docker daemon's process. The default value
for the flag is -500. This will allow the docker daemon to have a
less chance of being killed before containers do. The default value for
processes is 0 with a min/max of -1000/1000.
-500 is a good middle ground because it is less than the default for
most processes and still not -1000 which basically means never kill this
process in an OOM condition on the host machine. The only processes on
my machine that have a score less than -500 are dbus at -900 and sshd
and xfce( my window manager ) at -1000. I don't think docker should be
set lower, by default, than dbus or sshd so that is why I chose -500.

This ensures that:
- The in-memory plugin store is populated with all the plugins
- Plugins which were active before daemon restart are active after.
This utilizes the liverestore feature when available, otherwise it
manually starts the plugin.

Component: engine
This patch introduces a new experimental engine-level plugin management
with a new API and command line. Plugins can be distributed via a Docker
registry, and their lifecycle is managed by the engine.
This makes plugins a first-class construct.
For more background, have a look at issue #20363.
Documentation is in a separate commit. If you want to understand how the
new plugin system works, you can start by reading the documentation.
Note: backwards compatibility with existing plugins is maintained,
albeit they won't benefit from the advantages of the new system.

This PR is fully backward compatible (joining a Swarm is an optional
feature of the Engine, and existing commands are not impacted).

This flags enables full support of daemonless containers in docker. It
ensures that docker does not stop containers on shutdown or restore and
properly reconnects to the container when restarted.
This is not the default because of backwards compat but should be the
desired outcome for people running containers in prod.

Using golang 1.6, is it now possible to ignore SIGPIPE events on
stdout/stderr. Previous versions of the golang library cached 10
events and then killed the process receiving the events.
systemd-journald sends SIGPIPE events when jounald is restarted and
the target of the unit file writes to stdout/stderr. Docker logs to stdout/stderr.
This patch silently ignores all SIGPIPE events.
