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.

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.

This means that plugins can use whatever methods the monolithic CLI supports,
which is good for consistency.
This relies on `os.Args[0]` being something which can be executed again to
reach the same binary, since it is propagated (via an envvar) to the plugin for
this purpose. This essentially requires that the current working directory and
path are not modified by the monolithic CLI before it launches the plugin nor
by the plugin before it initializes the client. This should be the case.
Previously the fake apiclient used by `TestExperimentalCLI` was not being used,
since `cli.Initialize` was unconditionally overwriting it with a real one
(talking to a real daemon during unit testing, it seems). This wasn't expected
nor desirable and no longer happens with the new arrangements, exposing the
fact that no `pingFunc` is provided, leading to a panic. Add a `pingFunc` to
the fake client to avoid this.

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`.

- The `/build/prune` endpoint was added in API v1.31
- The `/network` endpoints were added in API v1.21
This patch hides these commands on older API versions
Before this change:
```
DOCKER_API_VERSION=1.0 docker
...
Management Commands:
builder Manage builds
container Manage containers
image Manage images
manifest Manage Docker image manifests and manifest lists
network Manage networks
system Manage Docker
trust Manage trust on Docker images
```
After this change
```
DOCKER_API_VERSION=1.0 docker
...
Management Commands:
container Manage containers
image Manage images
manifest Manage Docker image manifests and manifest lists
system Manage Docker
trust Manage trust on Docker images
```

I authored this for `contentTrustEnabled` prior to 7f207f3f95, so this now
tests the funcation argument version.

This helps to avoid circular includes, by separating the pure data out from the
actual functionality in the cli subpackage, allowing other code which is
imported to access the data.

All of the current callers follow the pattern:
dockerPreRun(opts)
err := dockerCli.Initialize(opts) ...
So there is no semantic change into merging the content of `dockerPreRun` into the head of `Initialize`.
I'm about to add a new caller outside of the `cmd/docker` package and this
seems preferable exporting `DockerPreRun`.

This will allow plugins to have custom typed endpoints, as well as
create/remove/update contexts with the exact same results as the main
CLI (thinking of things like `docker ee login https://my-ucp-server
--context ucp-prod)`

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
manual errors. The docs were edited the same way.

Right now the only client side info we have is whether debug is enabled, but we
expect more in the future.
We also preemptively prepare for the possibility of multiple errors when
gathering both daemon and client info.
