Having `resource` and `action` is redundant.

`action` is used when the parent class containing the commands has `resource` declared. Organization is a bit weird because it shares commands between Foreman and Katello.

using `resource` in your command class:
```ruby
class FooCommand< HammerCLIKatello::ListCommand
  resource :foos, :list
  # ...
end
```

compared to having a parent command with `resource` already defined:
```ruby
class FooParent < HammerCLIKatello::Command
  resource :foos

  class ListCommand < HammerClIKatello::ListCommand
    action :list
    # ...
  end

  class ShowCommand < HammerCLIKatello::InfoCommand
    action :show
    # ...
  end

end
```

I would stick with just `resource :organizations, :action_name` here because the parent Organization command class doesn't have a `resource` declared.
