The `ENV key value` form can be ambiguous, for example, the following defines
a single env-variable (`ONE`) with value `"TWO= THREE=world"`:
ENV ONE TWO= THREE=world
While we cannot deprecate/remove that syntax (as it would break existing
Dockerfiles), we should reduce exposure of the format in our examples.

The `docker push` command up until [v0.9.1](https://github.com/moby/moby/blob/v0.9.1/api/client.go#L998)
always pushed all tags of a given image, so `docker push foo/bar` would push (e.g.)
all of `foo/bar:latest`, `foo:/bar:v1`, `foo/bar:v1.0.0`.
Pushing all tags of an image was not desirable in many case, so docker v0.10.0
enhanced `docker push` to optionally specify a tag to push (`docker push foo/bar:v1`)
(see https://github.com/moby/moby/issues/3411 and the pull request that implemented
this: https://github.com/moby/moby/pull/4948).
This behavior exists up until today, and is confusing, because unlike other commands,
`docker push` does not default to use the `:latest` tag when omitted, but instead
makes it push "all tags of the image"
For example, in the following situation;
```
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
thajeztah/myimage latest b534869c81f0 41 hours ago 1.22MB
```
Running `docker push thajeztah/myimage` seemingly does the expected behavior (it
pushes `thajeztah/myimage:latest` to Docker Hub), however, it does not so for the
reason expected (`:latest` being the default tag), but because `:latest` happens
to be the only tag present for the `thajeztah/myimage` image.
If another tag exists for the image:
```
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
thajeztah/myimage latest b534869c81f0 41 hours ago 1.22MB
thajeztah/myimage v1.0.0 b534869c81f0 41 hours ago 1.22MB
```
Running the same command (`docker push thajeztah/myimage`) will push _both_ images
to Docker Hub.
> Note that the behavior described above is currently not (clearly) documented;
> the `docker push` reference documentation (https://docs.docker.com/engine/reference/commandline/push/)
does not mention that omitting the tag will push all tags
This patch changes the default behavior, and if no tag is specified, `:latest` is
assumed. To push _all_ tags, a new flag (`-a` / `--all-tags`) is added, similar
to the flag that's present on `docker pull`.
With this change:
- `docker push myname/myimage` will be the equivalent of `docker push myname/myimage:latest`
- to push all images, the user needs to set a flag (`--all-tags`), so `docker push --all-tags myname/myimage:latest`

A while ago, Docker split the "Domainname" field out from the "Hostname"
field for the container configuration. There was no real user-visible
change associated with this (and under the hood "Domainname" was mostly
left unused from the command-line point of view). We now add this flag
in order to match other proposed changes to allow for setting the NIS
domainname of a container.
This also includes a fix for the --hostname parsing tests (they would
not error out if only one of .Hostname and .Domainname were incorrectly
set -- which is not correct).

I am attempting to push a tag to a private repository. The documentation for `docker tag` has an explicit example to for how ["To push an image to a private registry"](https://docs.docker.com/engine/reference/commandline/tag/#tag-an-image-referenced-by-name). My colleague clarified that this command does not in fact push anything, so I thought this PR might save some future novice the same confusion.

Previously our man pages included the current time each time they were
generated. This causes an issue for reproducible builds, since each
re-build of a package that includes the man pages will have different
times listed in the man pages.
To fix this, add support for SOURCE_DATE_EPOCH (which is a standardised
packaging environment variable, designed to be used specifically for
this purpose[1]). spf13/cobra doesn't support this natively yet (though
I will push a patch for that as well), but it's simpler to fix it
directly in docker/cli.

The --allow-nondistributable-artifacts daemon option specifies
registries to which foreign layers should be pushed. (By default,
foreign layers are not pushed to registries.)
Additionally, to make this option effective, foreign layers are now
pulled from the registry if possible, falling back to the URLs in the
image manifest otherwise.
This option is useful when pushing images containing foreign layers to a
registry on an air-gapped network so hosts on that network can pull the
images without connecting to another server.

This is synonymous with `docker run --cidfile=FILE` and writes the digest of
the newly built image to the named file. This is intended to be used by build
systems which want to avoid tagging (perhaps because they are in CI or
otherwise want to avoid fixed names which can clash) by enabling e.g. Makefile
constructs like:
image.id: Dockerfile
docker build --iidfile=image.id .
do-some-more-stuff: image.id
do-stuff-with <image.id
Currently the only way to achieve this is to use `docker build -q` and capture
the stdout, but at the expense of losing the build output.
In non-silent mode (without `-q`) with API >= v1.29 the caller will now see a
`JSONMessage` with the `Aux` field containing a `types.BuildResult` in the
output stream for each image/layer produced during the build, with the final
one being the end product. Having all of the intermediate images might be
interesting in some cases.
In silent mode (with `-q`) there is no change, on success the only output will
be the resulting image digest as it was previosuly.
There was no wrapper to just output an Aux section without enclosing it in a
Progress, so add one here.
Added some tests to integration cli tests.

Instead of forcing users to manually configure a block device to use
with devmapper, this gives the user the option to let the devmapper
driver configure a device for them.
Adds several new options to the devmapper storage-opts:
- dm.directlvm_device="" - path to the block device to configure for
direct-lvm
- dm.thinp_percent=95 - sets the percentage of space to use for
storage from the passed in block device
- dm.thinp_metapercent=1 - sets the percentage of space to for metadata
storage from the passed in block device
- dm.thinp_autoextend_threshold=80 - sets the threshold for when `lvm`
should automatically extend the thin pool as a percentage of the total
storage space
- dm.thinp_autoextend_percent=20 - sets the percentage to increase the
thin pool by when an autoextend is triggered.
Defaults are taken from
[here](https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/#/configure-direct-lvm-mode-for-production)
The only option that is required is `dm.directlvm_device` for docker to
set everything up.
Changes to these settings are not currently supported and will error
out.
Future work could support allowing changes to these values.

This fix tries to address the request in 31324 by adding
`--filter scope=swarm|local` for `docker network ls`.
As `docker network ls` has a `SCOPE` column by default,
it is natural to add the support of `--filter scope=swarm|local`.
This fix adds the `scope=swarm|local` support for
`docker network ls --filter`.
