Native CodePipline steps

[sholtomaud]

Use case

granted this seems to be beta phase in development, but it would be good to remove the step functions from the pipeline

Solution/User Experience

step functions in pipelines are a temporary solution to something that should be native/built-in steps/actions in CodePipeline.

This will make for a more standard pipeline flow without the need for custom step functions.
