Removing a host by `<host>:<ip>` should only remove occurences of the host with
a matching IP-address, instead of removing all entries for that host.
In addition, combining `--host-rm` and `--host-add` for the same host should
result in the new host being added.
This patch fixes the way the diff is calculated to allow combining
removing/adding, and to support entries having both a canonical, and aliases.
Aliases cannot be added by the CLI, but are supported in the Service spec, thus
should be taken into account:
Entries can be removed by either a specific `<host-name>:<ip-address>`
mapping, or by `<host>` alone:
- If both IP-address and host-name is provided, only remove the hostname
from entries that match the given IP-address.
- If only a host-name is provided, remove the hostname from any entry it
is part of (either as _canonical_ host-name, or as _alias_).
- If, after removing the host-name from an entry, no host-names remain in
the entry, the entry itself should be removed.
For example, the list of host-entries before processing could look like this:
hosts = &[]string{
"127.0.0.2 host3 host1 host2 host4",
"127.0.0.1 host1 host4",
"127.0.0.3 host1",
"127.0.0.1 host1",
}
Removing `host1` removes every occurrence:
hosts = &[]string{
"127.0.0.2 host3 host2 host4",
"127.0.0.1 host4",
}
Whereas removing `host1:127.0.0.1` only remove the host if the IP-address matches:
hosts = &[]string{
"127.0.0.2 host3 host1 host2 host4",
"127.0.0.1 host4",
"127.0.0.3 host1",
}
Before this patch:
$ docker service create --name my-service --host foo:127.0.0.1 --host foo:127.0.0.2 --host foo:127.0.0.3 nginx:alpine
$ docker service update --host-rm foo:127.0.0.1 --host-add foo:127.0.0.4 my-service
$ docker service inspect --format '{{.Spec.TaskTemplate.ContainerSpec.Hosts}}' my-service

The "update" and "rollback" configurations were cross-wired, as a result, setting
`--rollback-*` options would override the service's update-options.
Creating a service with both update, and rollback configuration:
docker service create \

--update-failure-action=pause \
--update-max-failure-ratio=0.6 \
--update-monitor=3s \

--update-parallelism=3 \

--rollback-max-failure-ratio=0.5 \
--rollback-monitor=4s \
--rollback-order=start-first \
--rollback-parallelism=2 \

`--label-file` has the exact same behavior as `--env-file`, meaning any
placeholder (i.e. a simple key, no `=` sign, no value), it will get the
value from the environment variable.
For `--label-file` it should just add an empty label.

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

$ docker network create -d overlay foo
$ docker service create --name=test --network=foo nginx:alpine
$ docker service update --network-add foo test

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.

Commit 330a0035334871d92207b583c1c36d52a244753f added a `--detach=false` option
to various service-related commands, with the intent to make this the default in
a future version (17.09).
This patch changes the default to use "interactive" (non-detached), allowing
users to override this by setting the `--detach` option.
To prevent problems when connecting to older daemon versions (17.05 and below,
see commit db60f25561), the detach option is
ignored for those versions, and detach is always true.
Before this change, a warning was printed to announce the upcoming default:
$ docker service create nginx:alpine
saxiyn3pe559d753730zr0xer
Since --detach=false was not specified, tasks will be created in the background.
In a future release, --detach=false will become the default.
After this change, no warning is printed, but `--detach` is disabled;
$ docker service create nginx:alpine
y9jujwzozi0hwgj5yaadzliq6
overall progress: 1 out of 1 tasks
1/1: running [==================================================>]
verify: Service converged
Setting the `--detach` flag makes the cli use the pre-17.06 behavior:
$ docker service create --detach nginx:alpine
280hjnzy0wzje5o56gr22a46n
Running against a 17.03 daemon, without specifying the `--detach` flag;
$ docker service create nginx:alpine
