Running `docker stack services <STACK> --orchestrator swarm would yield
the message "Noting found in stack: asdf" with an exit code 0. The same
command with kubernetes orchestrator would yield "nothing found in
stack: adsf" (note the lower-case "nothing") and a non-zero exit code.
This change makes the `stack services` command uniform for both
orchestrators. The logic of getting and printing services is split to
reuse the same formatting code.

API v1.41 adds a new option to get the number of desired
and running tasks when listing services. This patch enables
this functionality, and provides a fallback mechanism when
the ServiceStatus is not available, which would be when
using an older API version.
Now that the swarm.Service struct captures this information,
the `ListInfo` type is no longer needed, so it is removed,
and the related list- and formatting functions have been
modified accordingly.
To reduce repetition, sorting the services has been moved
to the formatter. This is a slight change in behavior, but
all calls to the formatter performed this sort first, so
the change will not lead to user-facing changes.

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 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`.

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.

networks are set);
- `--ip`
- `--ip6`
- `--link`
- `--link-local-ip`

In the initial implementation I thought it would be good to not pass on the
deprecation to plugins (since they are new). However it turns out this causes
`docker helloworld -h` to print a spurious "pflag: help requested" line:
$ docker helloworld -h
pflag: help requested
See 'docker helloworld --help'.
Usage: docker helloworld [OPTIONS] COMMAND
A basic Hello World plugin for tests
...
Compared with:
$ docker ps -h
Flag shorthand -h has been deprecated, please use --help
Usage: docker ps [OPTIONS]
This is in essence because having the flag undefined hits a different path
within cobra, causing `c.execute()` to return early due to getting an error
(`flag.ErrHelp`) from `c.ParseFlags`, which launders the error through our
`FlagErrorFunc` which wraps it in a `StatusError` which in turn defeats an `if
err == flag.ErrHelp` check further up the call chain. If the flag is defined we
instead hit a path which returns a bare `flag.ErrHelp` without wrapping it.
I considered updating our `FlagErrorFunc` to not wrap `flag.ErrHelp` (and then
following the chain to the next thing) however while doing that I realised that
the code for `-h` (and `--help`) is deeply embedded into cobra (and its flags
library) such that actually using `-h` as a plugin argument meaning something
other than `help` is basically impossible/impractical. Therefore we may as well
have plugins behave identically to the monolithic CLI and support (deprecated)
the `-h` argument.
With this changed the help related blocks of `SetupRootCommand` and
`SetupPluginRootCommand` are now identical, so consolidate into
`setupCommonRootCommand`.
Tests are updated to check `-h` in a variety of scenarios, including the happy
case here.

As pointed out in #1459, docker cli fails to detect that the input is a tarball,

This happens because `git archive` adds some metadata to the initial tar header,

to archive/tar.Next() and it fails.
To fix, give it 2 blocks :)

This patch fixes a bug where labels use the same behavior as `--env`, resulting
in a value to be copied from environment variables with the same name as the
label if no value is set (i.e. a simple key, no `=` sign, no value).
An earlier pull request addressed similar cases for `docker run`;
2b17f4c8a8, but this did not address the
same situation for (e.g.) `docker service create`.
Digging in history for this bug, I found that use of the `ValidateEnv`
function for labels was added in the original implementation of the labels feature in
abb5e9a077 (diff-ae476143d40e21ac0918630f7365ed3cR34)
However, the design never intended it to expand environment variables,
and use of this function was either due to either a "copy/paste" of the
equivalent `--env` flags, or a misunderstanding (the name `ValidateEnv` does
not communicate that it also expands environment variables), and the existing
`ValidateLabel` was designed for _engine_ labels (which required a value to
be set).
Following the initial implementation, other parts of the code followed
the same (incorrect) approach, therefore leading the bug to be introduced
in services as well.
This patch:
- updates the `ValidateLabel` to match the expected validation
rules (this function is no longer used since 31dc5c0a9a),
and the daemon has its own implementation)
- corrects various locations in the code where `ValidateEnv` was used instead of `ValidateLabel`.
Before this patch:
```bash
export SOME_ENV_VAR=I_AM_SOME_ENV_VAR
docker service create --label SOME_ENV_VAR --tty --name test busybox
docker service inspect --format '{{json .Spec.Labels}}' test
{"SOME_ENV_VAR":"I_AM_SOME_ENV_VAR"}
```
After this patch:
```bash
export SOME_ENV_VAR=I_AM_SOME_ENV_VAR
docker service create --label SOME_ENV_VAR --tty --name test busybox
docker container inspect --format '{{json .Config.Labels}}' test
{"SOME_ENV_VAR":""}
