## Background
Refer [this](https://tinyurl.com/skaffold-modules) document which presents the design goals for introducing the concept of _modules_ in Skaffold. A prerequisite to being able to define modules and supporting cross module dependency is to first consider the latest version of the skaffold config (_currently `v2beta8`_) as an implicit module and allowing dependencies between artifacts defined in it. The current document aims to capture the major code changes necessary for achieving this.
