As for top-level key, any 3rd-level key which starts with `x-` will be
ignored by compose. This allows for users to:
* include additional metadata in their compose files
* create YAML anchor objects that can be re-used in other parts of the config
This matches a similar feature in the swagger spec definition:
https://swagger.io/specification/#specificationExtensions
This means a composefile like the following is valid
```
verison: "3.7"
services:
foo:
image: foo/bar
x-foo: bar
network:
bar:
x-bar: baz
```
It concerns services, volumes, networks, configs and secrets.

Since go 1.7, "context" is a standard package. Since go 1.9,
x/net/context merely provides some types aliased to those in
the standard context package.
The changes were performed by the following script:
for f in $(git ls-files \*.go | grep -v ^vendor/); do
sed -i 's|golang.org/x/net/context|context|' $f
goimports -w $f
for i in 1 2; do
awk '/^$/ {e=1; next;}
/\t"context"$/ {e=0;}
{if (e) {print ""; e=0}; print;}' < $f > $f.new && \
mv $f.new $f
goimports -w $f
done
done
[v2: do awk/goimports fixup twice]

… and other cases too. Updating mergo fixes the bugs (but introduced a
slight behaviour change that had to be fixed too)

Some of them are skipped for now (because the feature is not supported
or needs more work), some of them are fixed.

- Add `Version` to `types.Config`
- Add a new `Services` types (that is just `[]ServiceConfig`) and add
`MarshalYAML` method on it.
- Clean other top-level custom marshaling as `Services` is the only one
required.

To ensure we are loading the composefile the same wether we are pointing
to swarm or kubernetes, we need to share the loading code between both.

Services do not support custom "pid"-modes (e.g. `--pid=host`), but this
option was ignored silently when deploying a stack.
This patch adds `pid` to the list of unsupported options so that a warning
is printed;
With this patch applied:
$ docker stack deploy -c docker-compose.yml foobar
Ignoring unsupported options: pid

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.
