The State field allows printing the container state without
additional information about uptime, healthcheck, etc.
With this patch, the container's state can be printed independently:

exited
created
```
```bash
docker ps -a --format 'table {{.Names}}\t{{.State}}\t{{.Status}}'

When deploying a stack using a relative path as bind-mount
source in the compose file, the CLI converts the relative
path to an absolute path, relative to the location of the
docker-compose file.
This causes a problem when deploying a stack that uses
an absolute Windows path, because a non-Windows client will
fail to detect that the path (e.g. `C:\somedir`) is an absolute
path (and not a relative directory named `C:\`).
The existing code did already take Windows clients deploying
a Linux stack into account (by checking if the path had a leading
slash). This patch adds the reverse, and adds detection for Windows
absolute paths on non-Windows clients.
The code used to detect Windows absolute paths is copied from the
Golang filepath package;

This partially reverts e0b59ab52b,
and does not automatically disable proxying signals in TTY-mode
Before this change:
------------------------------------
Start a container with a TTY in one shell:
```
docker run -it --init --name repro-28872 busybox sleep 30
```
then, in another shell, kill the docker cli:
```
kill `pgrep -f repro-28872`
```
Notice that the CLI was killed, but the signal not forwarded to the container;
the container continues running
```
docker container inspect --format '{{ .State.Status }}' repro-28872
running
docker container rm -f repro-28872
```
After this change:
------------------------------------
Start a container with a TTY in one shell:
```
docker run -it --init --name repro-28872 busybox sleep 30
```
then, in another shell, kill the docker cli:
```
kill `pgrep -f repro-28872`
```
Verify that the signal was forwarded to the container, and the container exited
```
docker container inspect --format '{{ .State.Status }}' repro-28872
exited
docker container rm -f repro-28872
```

This code was attempting to check Linux file permissions
to determine if the key was accessible by other users, which
doesn't work, and therefore prevented users on Windows
to load keys.

were already skipped).

For backward compatibility: if no custom options are provided for the network,
and only a single network is specified, omit the endpoint-configuration
on the client (the daemon will still create it when creating the container)
This fixes an issue on older versions of legacy Swarm, which did not support
`NetworkingConfig.EndpointConfig`.
This was introduced in 5bc09639cc (#1767)

Adds capabilities to import a .zip file with importZip.
Detects the content type of source by checking bytes & DetectContentType.
Adds LimitedReader reader, a fork of io.LimitedReader,
was needed for better error messaging instead of just getting back EOF.
We are using limited reader to avoid very big files causing memory issues.
Adds a new file size limit for context imports,
this limit is used for the main file for .zip & .tar and individual compressed
files for .zip.
Added TestImportZip that will check the import content type
Then will assert no err on Importing .zip file

This is less of a layering violation and removes some ugly hardcoded
`"kubernetes"` strings which were needed to avoid an import loop.
Signed-off-by: Ian Campbell <ijc@docker.com>
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 reverts commit 59defcb34d which caused #1892
since the timeout applied not only to the dial phase but to everything, so it
would kill `docker logs -f ...` if the container was not chatty enough.

The comment on `github.com/docker/cli/kubernetes.NewKubernetesConfig` said:
// Deprecated: Use github.com/docker/compose-on-kubernetes/api.NewKubernetesConfig instead
By making this switch in `github.com/docker/cli/context/kubernetes/load.go` we
break a vendoring chain:
`github.com/docker/cli/cli/command`
→ `vendor/github.com/docker/cli/cli/context/kubernetes/load.go`
→ `vendor/github.com/docker/cli/kubernetes`
→ `github.com/docker/compose-on-kubernetes/api/compose/...`
This means that projects which just want `github.com/docker/cli/cli/command`
(which is itself pulled in transitively by
`github.com/docker/cli/cli-plugins/plugin`) which do not themselves need the
compose-on-kubernetes API avoid a huge pile of transitive dependencies.
On one of my private projects the diff on the vendor dir is:
280 files changed, 21 insertions(+), 211346 deletions(-)
and includes dropping:
* `github.com/docker/compose-on-kubernetes/api/compose/{clone,impersonation}`
* `github.com/docker/compose-on-kubernetes/api/compose/{v1alpha3,v1beta1,v1beta2,v1beta3}`
* `github.com/google/btree`
* `github.com/googleapis/gnostic`
* `github.com/gregjones/httpcache`
* `github.com/peterbourgon/diskv`
* `k8s.io/api/*` (_lots_ of subpackages)
* `k8s.io/client-go/{discovery,kubernetes/scheme}`
and I've gone from:
$ du -sh vendor/k8s.io/
8.1M vendor/k8s.io/
to:
$ du -sh vendor/k8s.io/
2.1M vendor/k8s.io/
(overall I went from 36M → 29M of vendor dir for this particular project)
The change to `cli/command/system/version.go` is just for consistency and
allows us to drop the now unused alias.

Refactor `RunCreate` slightly so that all three paths always produce the same
output, namely the name of the new context of `stdout` (for scripting) and the
success log message on `stderr`.
Validate by extending the existing unit tests to always check the output is as
expected.

This partially mitigates #1739 ("Docker commands take 1 minute to timeout if
context endpoint is unreachable") and is a simpler alternative to #1747 (which
completely defers the client connection until an actual call is attempted).
Note that the previous 60s delay was the culmination of two separate 30s
timeouts since the ping is tried twice. This with this patch the overall
timeout is 20s. https://github.com/moby/moby/pull/39206 will remove the second
ping and once that propagates to this tree the timeout will be 10s.
