Following #22729, enable to dynamically reload/remove the daemon
authorization plugins (via standard reloading mechanism).

configuration-file
Daemon must store a reference to the authorization middleware to refresh
the plugin on configuration changes.

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 adds the `--live-restore` option to the documentation.
Also synched usage description in the documentation
with the actual description, and re-phrased some
flag descriptions to be a bit more consistent.

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 fix tries to address issues raised in #20936 and #22443
where `docker pull` or `docker push` fails because of the
concurrent connection failing.
Currently, the number of maximum concurrent connections is
controlled by `maxDownloadConcurrency` and `maxUploadConcurrency`
which are hardcoded to 3 and 5 respectively. Therefore, in
situations where network connections don't support multiple
downloads/uploads, failures may encounter for `docker push`
or `docker pull`.
This fix tries changes `maxDownloadConcurrency` and
`maxUploadConcurrency` to adjustable by passing
`--max-concurrent-uploads` and `--max-concurrent-downloads` to
`docker daemon` command.
The documentation related to docker daemon has been updated.
Additional test case have been added to cover the changes in this fix.
This fix fixes#20936. This fix fixes#22443.
