I noticed that we're using a homegrown package for assertions. The
functions are extremely similar to testify, but with enough slight
differences to be confusing (for example, Equal takes its arguments in a
different order). We already vendor testify, and it's used in a few
places by tests.
I also found some problems with pkg/testutil/assert. For example, the
NotNil function seems to be broken. It checks the argument against
"nil", which only works for an interface. If you pass in a nil map or
slice, the equality check will fail.
In the interest of avoiding NIH, I'm proposing replacing
pkg/testutil/assert with testify. The test code looks almost the same,
but we avoid the confusion of having two similar but slightly different
assertion packages, and having to maintain our own package instead of
using a commonly-used one.
In the process, I found a few places where the tests should halt if an
assertion fails, so I've made those cases (that I noticed) use "require"
instead of "assert", and I've vendored the "require" package from
testify alongside the already-present "assert" package.

None of the daemon flags use a constant for the
flag name.
This patch removes the constant for consistency
Also removes a FIXME, that was now in the wrong
location, and added a long time ago in
353b7c8ec7,
without a lot of context (and probably no longer really relevant).

Even though the flag `--api-enable-cors` is deprecated in favor of
`--api-cors-header`. Using only `--api-cors-header` does not enable
CORS.
Make changes to 'cmd/dockerd/daemon.go' to enable cors if either of
the above flags is set.

When the daemon is configured to run with an authorization-plugin and if
the plugin is disabled, the daemon continues to send API requests to the
plugin and expect it to respond. But the plugin has been disabled. As a
result, all API requests are blocked. Fix this behavior by removing the
disabled plugin from the authz middleware chain.
Tested using riyaz/authz-no-volume-plugin and observed that after
disabling the plugin, API request/response is functional.

The current error-handling only checked for version annotations
on the subcommand itself, but did not check the top-level command.
This patch always traverses the command path (parents), and
prints an error if the command is not supported.
Before this change:
$ docker service
Usage: docker service COMMAND
Manage services
Options:
--help Print usage
Commands:
create Create a new service
inspect Display detailed information on one or more services
ls List services
ps List the tasks of one or more services
rm Remove one or more services
scale Scale one or multiple replicated services
update Update a service
Run 'docker service COMMAND --help' for more information on a command.
$ docker service ls

After this change:
$ DOCKER_API_VERSION=1.12 docker service
docker service requires API version 1.24, but the Docker daemon API version is 1.12
$ DOCKER_API_VERSION=1.12 docker service ls
docker service ls requires API version 1.24, but the Docker daemon API version is 1.12
$ DOCKER_API_VERSION=1.24 docker plugin --help
docker plugin requires API version 1.25, but the Docker daemon API version is 1.24
$ DOCKER_API_VERSION=1.25 docker plugin upgrade --help
docker plugin upgrade requires API version 1.26, but the Docker daemon API version is 1.25

In more recent versions of Cobra, `--help` parsing is done before
anything else resulting in TestDaemonCommand not actually passing. I'm
actually unsure if this test ever passed since it appears that !daemon
is not being run as part of the test suite.

This fix is the follow up of the last commit.
In this fix:
1. If any of the parents of a command has tags, then this command's
`Args` (Args validation func) will be wrapped up. The warpped up func
will check to see if the feature is supported or not. If it is not supported,
then a not supported message is generated instead.
This fix is related to 28626.

This fix tries to address several issues raised in 28626 where
run against a non-experimental daemon may not generate correct
error message:
1. Incorrect flags were not checked against the supported features:
```
$ docker stack --nonsense
unknown flag: --nonsense
```
2. Subcommands were not checked against the supported features:
```
$ docker stack ls
Error response from daemon: This node is not a swarm manager...
```
This fix address the above mentioned issues by:
1. Add a pre-check for FlagErrorFunc
2. Recursively check if a feature is supported for cmd and its parents.
This fix fixes 28626.

Docker 1.13 and up allows a client to communicate
with older daemons. As a result, flags may be
present that are not supported by the older daemon.
The client already _hides_ flags that are not
supported yet, but this doesn't present users
from using those flags.
This change shows an error if a flag is used
that is not supported by the daemon (either
based on the API version, or because experimental
features are not enabled).
Note that for some options, a check is already
in place in the API client. For those
options, this is just a minor enhancement
to more clearly indicate which _flag_ is
not supported.
Before this change;
