Skaffold debug mode inconsistency with helm deployment strategy

[jycamier]

In my project, I decide to have a skaffold.yaml file configuration which is not called like that. It's just test.yaml.
Thanks to --filename option, I can do it.

However, with the helm deployment strategy on debug mode, you add the helm's options --post-renderer which is
/usr/local/bin/skaffold but without --filename option and you cannot.

Expected behavior

I would like to use debug mode without a config file which is madatory called skaffold.yaml
Moreover, I use sometimes kustomize in helm --post-renderer. How I can do it with the debug mode ?

Actual behavior

skaffold -f test.yaml debug
