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/

When initializing the API client, the User-Agent was added to any custom
HTTPHeaders that were configured. However, because the map was not properly
dereferenced, the original map was modified, causing the User-Agent to also
be saved to config.json after `docker login` and `docker logout`:

- Perform feature detection when actually needed, instead of during
initializing
- Version negotiation is performed either when making an API request,
or when (e.g.) running `docker help` (to hide unsupported features)
- Use a 2 second timeout when 'pinging' the daemon; this should be
sufficient for most cases, and when feature detection failed, the
daemon will still perform validation (and produce an error if needed)
- context.WithTimeout doesn't currently work with ssh connections (connhelper),
so we're only applying this timeout for tcp:// connections, otherwise
keep the old behavior.

Possible approach for client info
- split ClientInfo() into ClientInfo() and loadClientInfo()
- split ConfigFile() into ConfigFile() and loadConfigFile()
- ConfigFile() and ClientInfo() call their corresponding loadXX function
if it has not yet been loaded; this allows them to be used before
Initialize() was called.
- Initialize() *always* (re-)loads the configuration; this makes sure
that the correct configuration is used when actually calling commands.

This removes the need for the core context code to import
`github.com/docker/cli/cli/context/kubernetes` which in turn reduces the
transitive import tree in this file to not pull in all of Kubernetes.
Note that this means that any calling code which is interested in the
kubernetes endpoint must import `github.com/docker/cli/cli/context/kubernetes`
itself somewhere in order to trigger the dynamic registration. In practice
anything which is interested in Kubernetes must import that package (e.g.
`./cli/command/context.list` does for the `EndpointFromContext` function) to do
anything useful, so this restriction is not too onerous.
As a special case a small amount of Kubernetes related logic remains in
`ResolveDefaultContext` to handle error handling when the stack orchestrator
includes Kubernetes. In order to avoid a circular import loop this hardcodes
the kube endpoint name.
Similarly to avoid an import loop the existing `TestDefaultContextInitializer`
cannot continue to unit test for the Kubernetes case, so that aspect of the
test is carved off into a very similar test in the kubernetes context package.
Lastly, note that the kubernetes endpoint is now modifiable via
`WithContextEndpointType`.

These are needed by any dynamically registered (via
`RegisterDefaultStoreEndpoints`) endpoint type to write a useful/sensible unit
test.
Signed-off-by: Ian Campbell <ijc@docker.com>
Previously an endpoint registered using `RegisterDefaultStoreEndpoints` would
not be taken into consideration by `resolveDefaultContext` and so could not
provide any details.
Resolve this by passing a `store.Config` to `resolveDefaultContext` and using
it to iterate over all registered endpoints. Any endpoint can ensure that their
type implements the new `EndpointDefaultResolver` in order to provide a default.
The Docker and Kubernetes endpoints are special cased, shortly the Kubernetes
one will be refactored to be dynamically registered.

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.

This helps to avoid circular includes, by separating the pure data out from the

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`.

Enable inspection (aka "shallow pull") of images' manifest info, and
also the creation of manifest lists (aka "fat manifests").
The workflow for creating a manifest list will be:
`docker manifest create new-list-ref-name image-ref [image-ref...]`
`docker manifest annotate new-list-ref-name image-ref --os linux --arch
arm`
`docker manifest push new-list-ref-name`
The annotate step is optional. Most architectures are fine by default.
There is also a `manifest inspect` command to allow for a "shallow pull"
of an image's manifest: `docker manifest inspect
manifest-or-manifest_list`.
To be more in line with the existing external manifest tool, there is
also a `-v` option for inspect that will show information depending on
what the reference maps to (list or single manifest).

Some network environments may have NATs, proxies, or gateways which
kill idle connections. There are many Docker API operations which may
be idle for long periods of time (such as ContainerWait and ContainerAttach)
and may result in unexpected connection closures or hangs if TCP keepalives
are not used.
This patch updates the default HTTP transport used by the Docker client
package to enable TCP Keep-Alive with a keep-alive interval of 30 seconds.
It also sets a connect timeout of 30 seconds.
