Yong Tang 8e688f17a3 Improve error handling of experimental features in non-experimental mode ...

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.
