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

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;
DOCKER_API_VERSION=1.24 docker run -d --stop-timeout=30 busybox top
mjfyt3qpvnq0iwmun3sjwth9i
echo -e "FROM busybox\nRUN echo foo > bar" | DOCKER_API_VERSION=1.24 docker build --squash -
"squash" requires API version 1.25, but the Docker server is version 1.24
After this change;
DOCKER_API_VERSION=1.24 docker run -d --stop-timeout=30 busybox top
"--stop-timeout" requires API version 1.25, but the Docker daemon is version 1.24
echo -e "FROM busybox\nRUN echo foo > bar" | DOCKER_API_VERSION=1.24 docker build --squash -
"--squash" requires API version 1.25, but the Docker daemon is version 1.24
echo -e "FROM busybox\nRUN echo foo > bar" | docker build --squash -
"--squash" is only supported on a Docker daemon with experimental features enabled
