add support for helm image convention vs fqn setting

[bivas]

This addresses the issue described in #360
It will enable the user to determine if the image setup schema is using fully qualified named vs the Helm standard of image.repository and image.tag

[wstrange]

Could we please see another release (9.1?) when this is merged!

[r2d4]

@bivas looks like this is a breaking change for the helm config, can we add this but default to the existing behavior?

@wstrange Once this gets in we'll do another release

[bivas]

@r2d4 Wouldn't it be better to default to the helm convention? I can fix the example to match the new default. I'm aware it will be a breaking change but it will support a much wider range of Helm charts.

[r2d4]

I don't want to break users current config, even if its really the right behavior. What do you think about leaving the default behavior as is for now, and then we can merge the feature, try it out, and migrate to skaffold/v1alpha3 config and swap the defaults?

[r2d4]

We can even use skaffold fix to perform that for users automatically

[bivas]

You're right. Better roll it slow and only enable for users who try the new version.

I'll update the behavior accordingly.

@r2d4 @dgageot Can we progress with this?

[r2d4]

Thanks!
