A Score is meant to be a very flexible, reusable component in Harmony. It describes a very specific action we apply on our Topology to prepare our environment as needed.

An ApplicationFeature is a higher level concept used to enrich how an Application is supposed to run on our environment.

Current behavior

Currently, as we can see for example in the ContinuousDelivery feature, each step is "harcoded" within the feature. It could be greatly improved if it was leveraging Scores to apply these actions instead. This could provide better progress tracking within the CLI as well, thanks to the automatic progress tracking of Scores.

Expected behavior

Add new scores when needed and use them to ensure the existing ApplicationFeature are installed properly.

For example for ContinuousDelivery, we could have a PackageHelmChartScore, PushHelmChartScore, BuildDockerImageScore, PushDockerImageScore, etc.
