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.

... in preference to `chsh`, since in recent alpine 3.9.2 images that can fail
with:
Password: chsh: PAM: Authentication token manipulation error
Which seems to relate to the use of `!` as the password for `root` in `/etc/shadow`gq

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.

Seems I rebased over b039db985a ("Make it possible to override the volume
mounts and shell for the dev container") at some point and failed to notice
that some of the variable names had changed.
In the meantime the underlying issue was fixed in #1698 but here we switch to
using `$(DOCKER_RUN)`. This means that these rules now use
`$(DOCKER_RUN_NAME_OPTION)` and thus obey the `$(DOCKER_CLI_CONTAINER_NAME)`
variable.

This patch switches the shellcheck image to use the official image
from Docker Hub.
Note that this does not yet update shellcheck to the latest version (v0.5.x);
Shellcheck v0.4.7 added some new checks, which makes CI currently fail, so will
be done in a follow-up PR. Instead, the v0.4.6 version is used in this PR, which
is closest to the same version as was installed in the image before this change;
```
docker run --rm docker-cli-shell-validate shellcheck --version
ShellCheck - shell script analysis tool
version: 0.4.4
license: GNU General Public License, version 3
website: http://www.shellcheck.net

Plugins are expected to be management commands ("docker <object> <verb>").
This patch modified the usage output to shown plugins in the "Management commands"
section.

This is a bit manual (as the unit test attests) so we may find we want to add
some helpers/accessors, but this is enough to let plugins use it and to
preserve the information through round-trips.

- The placement of the vendor is now in the end of the line.
- A '*' is now added as suffix of plugins' top level commands.

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.
