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`.

Previously a plugin which used these hooks would overwrite the top-level plugin
command's use of this hook, resulting in the dockerCli object not being fully
initialised.
Provide a function which plugins can use to chain to the required behaviour.
This required some fairly ugly arrangements to preserve state (which was
previously in-scope in `newPluginCOmmand`) to be used by the new function.

To achieve this we hook in at the beginning of our custom `HelpFunc` and detect
the plugin case by adding stub commands.

To do this we add a stub `cobra.Command` for each installed plugin (only when
invoking `help`, not for normal running).
This requires a function to list all available plugins so that is added here.

To help with this add a bad plugin which produces invalid metadata and arrange
for it to be built in the e2e container.

Also includes the scaffolding for finding a validating plugin candidates.
Argument validation is moved to RunE to support this, so `noArgs` is removed.

That is, the helper to be used from the plugin's `main`.
Also add a `helloworld` plugin example and build integration.

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.

... and expose. I would like to use this from another site.
This implies also moving (and exposing) the `visitAll` helper.
Unit test them while I'm here.

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.

Last batch of modifications to the context switch implementation missed
some documentation updates. This is an update to the CLI reference and
the store implementation Godoc.
