Errors always need to go to stderr.
This also fixes a test in moby/moby's integration-cli which is checking
to see if errors connecting to the daemon are output on stderr.

The docker info output contains both "local" and "remote" (daemon-side) information.
The API endpoint to collect daemon information (`/info`) is known to be "heavy",
and (depending on what information is needed) not needed.
This patch checks if the template (`--format`) used requires information from the
daemon, and if not, omits making an API request.
This will improve performance if (for example), the current "context" is requested
from `docker info` or if only plugin information is requested.

The CLI disabled experimental features by default, requiring users
to set a configuration option to enable them.
Disabling experimental features was a request from Enterprise users
that did not want experimental features to be accessible.
We are changing this policy, and now enable experimental features
by default. Experimental features may still change and/or removed,
and will be highlighted in the documentation and "usage" output.
For example, the `docker manifest inspect --help` output now shows:
EXPERIMENTAL:
docker manifest inspect is an experimental feature.
Experimental features provide early access to product functionality. These features
may change between releases without warning or can be removed entirely from a future
release. Learn more about experimental features: https://docs.docker.com/go/experimental/

This adds the currently selected "docker context" to the output
of "docker version", which allows users to see which context
is selected to produce the version output, and can be used (for
example), to set the prompt to the currently selected context:
(in `~/.bashrc`):
```bash
function docker_context_prompt() {
PS1="context: $(docker version --format='{{.Client.Context}}')> "
}
PROMPT_COMMAND=docker_context_prompt
```
After reloading the `~/.bashrc`, the prompt now shows the currently selected
`docker context`:
```bash
$ source ~/.bashrc
context: default> docker context create --docker host=unix:///var/run/docker.sock my-context
my-context
Successfully created context "my-context"
context: default> docker context use my-context
my-context
Current context is now "my-context"
context: my-context> docker context use default
default
Current context is now "default"

The comment on `github.com/docker/cli/kubernetes.NewKubernetesConfig` said:
// Deprecated: Use github.com/docker/compose-on-kubernetes/api.NewKubernetesConfig instead
By making this switch in `github.com/docker/cli/context/kubernetes/load.go` we
break a vendoring chain:
`github.com/docker/cli/cli/command`
→ `vendor/github.com/docker/cli/cli/context/kubernetes/load.go`
→ `vendor/github.com/docker/cli/kubernetes`
→ `github.com/docker/compose-on-kubernetes/api/compose/...`
This means that projects which just want `github.com/docker/cli/cli/command`
(which is itself pulled in transitively by
`github.com/docker/cli/cli-plugins/plugin`) which do not themselves need the
compose-on-kubernetes API avoid a huge pile of transitive dependencies.
On one of my private projects the diff on the vendor dir is:
280 files changed, 21 insertions(+), 211346 deletions(-)
and includes dropping:
* `github.com/docker/compose-on-kubernetes/api/compose/{clone,impersonation}`
* `github.com/docker/compose-on-kubernetes/api/compose/{v1alpha3,v1beta1,v1beta2,v1beta3}`
* `github.com/google/btree`
* `github.com/googleapis/gnostic`
* `github.com/gregjones/httpcache`
* `github.com/peterbourgon/diskv`
* `k8s.io/api/*` (_lots_ of subpackages)
* `k8s.io/client-go/{discovery,kubernetes/scheme}`
and I've gone from:
$ du -sh vendor/k8s.io/
8.1M vendor/k8s.io/
to:
$ du -sh vendor/k8s.io/
2.1M vendor/k8s.io/
(overall I went from 36M → 29M of vendor dir for this particular project)
The change to `cli/command/system/version.go` is just for consistency and
allows us to drop the now unused alias.

The warning, printed before running `docker system prune` was printing the
filters in JSON format.
This patch attempts to make the output human readable;
- updating the code, and template to print filters individually
- reducing the indentation (which was quite deep)
Before this patch was applied;
```
docker system prune --filter until=24h --filter label=hello-world --filter label!=foo=bar --filter label=bar=baz
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all dangling build cache
- Elements to be pruned will be filtered with:
- label={"label":{"bar=baz":true,"hello-world":true},"label!":{"foo=bar":true},"until":{"24h":true}}
Are you sure you want to continue? [y/N]
```
With this patch applied;
```

The warning, printed before runing docker system prune was missing any filter
that was set in the configuration file. In addition, the warning prefixes the
filters with `label=`, which is no longer accurate, now that the prune command
also supports "until" as a filter.
Before this change, only the filters set on the command-line were shown,
and any filter set in the configuration file was missing;
```
mkdir -p ./test-config
echo '{"pruneFilters": ["label!=never=remove-me", "label=remove=me"]}' > test-config/config.json
docker --config=./test-config system prune --filter until=24h --filter label=hello-world --filter label!=foo=bar --filter label=bar=baz
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all dangling build cache
- Elements to be pruned will be filtered with:
- label={"label":{"bar=baz":true,"hello-world":true},"label!":{"foo=bar":true},"until":{"24h":true}}
Are you sure you want to continue? [y/N]
```
With this patch applied, both options from the commandline and options set
in the configuration file are shown;
```
mkdir -p ./test-config
echo '{"pruneFilters": ["label!=never=remove-me", "label=remove=me"]}' > test-config/config.json
docker --config=./test-config system prune --filter until=24h --filter label=hello-world --filter label!=foo=bar --filter label=bar=baz

This happens on Windows when dialing a named pipe (a path which is used by CLI
plugins), in that case some debugging shows:
DEBU[0000] conn is a *winio.win32MessageBytePipe
DEBU[0000] conn is a halfReadCloser: false
DEBU[0000] conn is a halfWriteCloser: true
the raw stream connection does not implement halfCloser
In such cases we can simply wrap with a nop function since closing for read
isn't too critical.
Signed-off-by: Ian Campbell <ijc@docker.com>
The `conn` here is `*winio.win32MessageBytePipe` which does not have a
`CloseRead` method (it does have `CloseWrite`) resulting in:
docker@WIN-NUC0 C:\Users\docker>.\docker-windows-amd64.exe system dial-stdio
the raw stream connection does not implement halfCloser
Also disable the path which uses this for cli-plugins on Windows.

Fairly straight forward. It became necessary to wrap `Plugin.Err` with a type
which implements `encoding.MarshalText` in order to have that field rendered
properly in the `docker info -f '{{json}}'` output.
Since I changed the type somewhat I also added a unit test for `formatInfo`.

That is, reindent the two sections by one space.
While the code was done by hand the `.golden` files had the extra space
inserted with emacs' `string-insert-rectangle` macro to (try to) avoid possible

This PR adds a store to the CLI, that can be leveraged to persist and
retrieve credentials for various API endpoints, as well as
context-specific settings (initially, default stack orchestrator, but we
could expand that).

for both Docker and Kubernetes APIs.
