Looks like the YAML conversion doesn't like lines starting with `[`, and
causing it to use the "compact" formatting in the generated YAML.
This patch un-wraps these lines to prevent this.

To create this, I ran every JSON document through `jq -S` (which sorts the keys and consistently pretty-prints the result in a format which matches the majority of documents in this file).

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/

If a file contains trailing whitespace, the YAML generator uses a
compact format, which is hard to read.

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.

When creating and updating services, we need to avoid unneeded service churn.
The interaction of separate lists to "add" and "drop" capabilities, a special
("ALL") capability, as well as a "relaxed" format for accepted capabilities
(case-insensitive, `CAP_` prefix optional) make this rather involved.
This patch updates how we handle `--cap-add` / `--cap-drop` when _creating_ as
well as _updating_, with the following rules/assumptions applied:
- both existing (service spec) and new (values passed through flags or in
the compose-file) are normalized and de-duplicated before use.
- the special "ALL" capability is equivalent to "all capabilities" and taken
into account when normalizing capabilities. Combining "ALL" capabilities
and other capabilities is therefore equivalent to just specifying "ALL".
- adding capabilities takes precedence over dropping, which means that if
a capability is both set to be "dropped" and to be "added", it is removed
from the list to "drop".
- the final lists should be sorted and normalized to reduce service churn
- no validation of capabilities is handled by the client. Validation is
delegated to the daemon/server.
When deploying a service using a docker-compose file, the docker-compose file
is *mostly* handled as being "declarative". However, many of the issues outlined
above also apply to compose-files, so similar handling is applied to compose
files as well to prevent service churn.

The output format was changed to combine tag and name in a single
column, but this change was never reflected in the docs.

This reflects a Moby change to add documentation around
disabling a new feature -- to use pgzip to decompress
layers, rather than the built-in go gzip.

This creates a new section of environment variables in the CLI docs
which documents environment variables that can both be used on dockerd
and on docker cli.
In addition, it moves some of the environment variable documentation
from the docker cli documentation to the dockerd documentation, as
these environment variables are dockerd-specific.

- replace the "none" code-hint with "console"
- some changes in the "experimental" instructions
- reformat some notes
- reformat / re-indent JSON output to use 2 spaces (for consistency)
- split JSON outputs to separate code-block so that it can be highlighted

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"
context: default>
```

Using `/var/run/docker.sock` as docker host is invalid, and causes
an error, so adding `unix://` to it.
In addition, we document the name of the context to go after the
options, so change the order in the examples.
