Kompose dependency is not included in skaffold or Cloud SDK

Cloud Code is using a model where we get our dependencies from Cloud SDK. Skaffold has a dependency on Kompose, but Kompose is not bundled with Skaffold or included in Cloud SDK. Therefore, Cloud Code has no good way to use Skaffold commands that are dependent on Kompose.

@briandealwis asked me to file this issue so we can discuss possible solutions. Changes may be made in Skaffold, Cloud Code, or Cloud SDK based on the outcome of the conversation here. I am just posting here because it is a Skaffold dependency we are unable to cleanly resolve.
