Prefer "strict" values for orchestrator, as it's
easier to add aliases (if we think it's needed) than
to remove them later.

When adding a network using `docker service update --network-add`,
the new network was added by _name_.
Existing entries in a service spec are listed by network ID, which
resulted in the CLI not detecting duplicate entries for the same
network.
This patch changes the behavior to always use the network-ID,
so that duplicate entries are correctly caught.
Before this change;
$ docker network create -d overlay foo
$ docker service create --name=test --network=foo nginx:alpine
$ docker service update --network-add foo test
$ docker service inspect --format '{{ json .Spec.TaskTemplate.Networks}}' test
[
{
"Target": "9ot0ieagg5xv1gxd85m7y33eq"
},
{
"Target": "9ot0ieagg5xv1gxd85m7y33eq"
}
]
After this change:
$ docker network create -d overlay foo
$ docker service create --name=test --network=foo nginx:alpine
$ docker service update --network-add foo test
service is already attached to network foo

Enable inspection (aka "shallow pull") of images' manifest info, and
also the creation of manifest lists (aka "fat manifests").
The workflow for creating a manifest list will be:
`docker manifest create new-list-ref-name image-ref [image-ref...]`
`docker manifest annotate new-list-ref-name image-ref --os linux --arch
arm`
`docker manifest push new-list-ref-name`
The annotate step is optional. Most architectures are fine by default.
There is also a `manifest inspect` command to allow for a "shallow pull"
of an image's manifest: `docker manifest inspect
manifest-or-manifest_list`.
To be more in line with the existing external manifest tool, there is
also a `-v` option for inspect that will show information depending on
what the reference maps to (list or single manifest).

Extra hosts (`extra_hosts` in compose-file, or `--hosts` in services) adds
custom host/ip mappings to the container's `/etc/hosts`.
The current implementation used a `map[string]string{}` as intermediate
storage, and sorted the results alphabetically when converting to a service-spec.
As a result, duplicate hosts were removed, and order of host/ip mappings was not
preserved (in case the compose-file used a list instead of a map).
According to the **host.conf(5)** man page (http://man7.org/linux/man-pages/man5/host.conf.5.html)
multi Valid values are on and off. If set to on, the resolver
library will return all valid addresses for a host that
appears in the /etc/hosts file, instead of only the first.
This is off by default, as it may cause a substantial
performance loss at sites with large hosts files.
Multiple entries for a host are allowed, and even required for some situations,
for example, to add mappings for IPv4 and IPv6 addreses for a host, as illustrated
by the example hosts file in the **hosts(5)** man page (http://man7.org/linux/man-pages/man5/hosts.5.html):
# The following lines are desirable for IPv4 capable hosts
127.0.0.1 localhost
# 127.0.1.1 is often used for the FQDN of the machine
127.0.1.1 thishost.mydomain.org thishost
192.168.1.10 foo.mydomain.org foo
192.168.1.13 bar.mydomain.org bar
146.82.138.7 master.debian.org master
209.237.226.90 www.opensource.org
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
This patch changes the intermediate storage format to use a `[]string`, and only
sorts entries if the input format in the compose file is a mapping. If the input
format is a list, the original sort-order is preserved.

The `--host-add` flag adds a new `host:ip` mapping. Even though
adding an entry is idempotent (adding the same mapping multiple
times does not update the service's definition), it does not
_update_ an existing mapping with a new IP-address (multiple
IP-addresses can be defined for a host).
This patch removes the "or update" part from the flag's
description.

Port mappings in `docker service ls` are quite verbose, and occupy a lot of
space when ranges of ports are published.
This patch improves the output by reconstructing ranges of ports.
Given the following service;
$ docker service create \
-p 60-61:60-61 \
-p 62:61 \
-p 80:80 \
-p 81:80 \
-p 90-95:90-95 \
-p 90-92:90-92/udp \
-p 93-96:93-96/udp \
--name foo \
nginx:alpine
Before this patch is applied:
$ docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
u1kwguv841qg foo replicated 1/1 nginx:alpine *:60->60/tcp,*:61->61/tcp,*:62->61/tcp,*:80->80/tcp,*:81->80/tcp,*:90->90/tcp,*:91->91/tcp,*:92->92/tcp,*:93->93/tcp,*:94->94/tcp,*:95->95/tcp,*:90->90/udp,*:91->91/udp,*:92->92/udp,*:93->93/udp,*:94->94/udp,*:95->95/udp,*:96->96/udp
After this patch is applied:
$ docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
u1kwguv841qg foo replicated 1/1 nginx:alpine *:60-62->60-61/tcp,*:80-81->80/tcp,*:90-95->90-95/tcp,*:90-96->90-96/udp
Additional enhancements can still be made, and marked as TODO in this change;
- combine non-consecutive ports mapped to a single port (`80->80`, `81->80`,
`84->80`, `86->80`, `87->80`); to be printed as `*:80-81,84,86-87->80`.
- combine `tcp` and `udp` mappings if their port-mapping is the same;
print `*:80-81->80-81/tcp+udp` instead of `*:80-81->80-81/tcp, *:80-81->80-81/udp`

The `docker container stats` output has a column (`CONTAINER`), that shows either
the container _id_ or container _name_, depending on the arguments given.
For example, running `docker container stats foobar` shows:
CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
foobar 0.00% 1.938MiB / 1.952GiB 0.10% 782B / 0B 4.11MB / 0B 2
Whereas `docker container stats 67b2525d8ad1` (`67b2525d8ad1` being the ID for
container `foobar`) shows:
CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
67b2525d8ad1 0.00% 1.938MiB / 1.952GiB 0.10% 916B / 0B 4.11MB / 0B 2
This behavior is confusing.
This patch updates the default output format for `docker stats` to use separate
columns for container ID and container Name (similar to `docker container ls`).
With this patch applied, both commands show the same output:
$ docker container stats foobar
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
67b2525d8ad10bb236a49960e93c09993b0baabeef12c2d46cd5f4fbb6f4808c foobar 0.00% 1.938MiB / 1.952GiB 0.10% 1.25kB / 0B 4.11MB / 0B 2
$ docker container stats 67b2525d8ad1
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
67b2525d8ad10bb236a49960e93c09993b0baabeef12c2d46cd5f4fbb6f4808c foobar 0.00% 1.938MiB / 1.952GiB 0.10% 1.31kB / 0B 4.11MB / 0B 2
Users that want to use the old format can configure a custom format in the
cli configuration file (`~/.docker/config.json`);
on Linux:
{
"statsFormat" : "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.MemPerc}}\t{{.NetIO}}\t{{.BlockIO}}\t{{.PIDs}}"
}
on Windows:
{
"statsFormat" : "table {{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.NetIO}}\t{{.BlockIO}}"
