Jonathan Boulle 87b3ad76c9 man/docker: wrap lines consistently
Quite a few changes, as it seems like previous wrapping was done
manually, so it's all over the place.

As noted in #28424

Yong Tang ef158e3e0a Add config parameter to change stop timeout during daemon shutdown
This fix tries to add a daemon config parameter `--shutdown-timeout`
that specifies the timeout value to stop containers gracefully
(before SIGKILL). The default value is 15s.

The `--shutdown-timeout` parameter is added to daemon options and
config file. It will also be updated during daemon reload.

Additional test cases have been added to cover the change.

This fix fixes #22471.

Michael Crosby d72deed554 Add init process for zombie fighting
This adds a small C binary for fighting zombies.  It is mounted under
`/dev/init` and is prepended to the args specified by the user.  You
enable it via a daemon flag, `dockerd --init`, as it is disable by
default for backwards compat.

You can also override the daemon option or specify this on a per
container basis with `docker run --init=true|false`.

You can test this by running a process like this as the pid 1 in a
container and see the extra zombie that appears in the container as it
is running.

```c

int main(int argc, char ** argv) {
	pid_t pid = fork();
	if (pid == 0) {
		pid = fork();
		if (pid == 0) {
			exit(0);
		}
		sleep(3);
		exit(0);
	}
	printf("got pid %d and exited\n", pid);
	sleep(20);
}
```

Aaron Lehmann 18cd5ac352 Split advertised address from listen address
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.

Michael Crosby bfe4e46682 Add --live-restore flag
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.

Yong Tang 9bc4cd536e Docker pull/push with max concurrency limits.
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.
