Help on subcommands doesn't work

[samtay]

Basked on this:

$ hueadm -h
...

  Generic Commands:
    help (?)        Help on a specific sub-command.

I expect to be able to run hueadm help create-schedule. But this just returns

$ hueadm help create-schedule
Create a schedule

Options:
    -h, --help      Show this help.
    -j, --json      JSON output.

which doesn't show how to use the subcommand.
